I'd rather have Cali emission laws than the ones we have in the county. Totally ridiculous. The only redeeming exemption is that you can get "collectors car" insurance for vehicles over 25 years old.
Keep it TOYOTA!

In the past years, I used to get a lot of calls from Jeep owners wanting to go slow like the Toy trucks.

I'm on the right track.  I put duct tape inside the throttle body, covering the IAC port, and folded the tape over the end of the throttle body so it could not get sucked in.  Engine would start and immediately die.  If I cracked the throttle just a bit, it would idle like a champ.

The factory manual specifies the resistance you should measure between the pins in the IAC valve connector.  On my original one, which was sitting on the bench, was way out of spec.  I couldn't be sure the one currently on the motor was out of spec, bc it's in such an awkward spot I couldn't be sure I was getting my meter on the pins correctly... but it appeared to also be out of spec.  So it appears I was dealing with two bad IAC valves.

Tomorrow I'll put in a new IAC valve and see what happens.

I hope that fixes it. It just seems wierd to have 2 bad ones. Just a note, I think our later model 3rz's have an IAC that is both mechanically and electronically controlled so it also provides idle up for the AC, power steering and possibly other things

GREAT NEWS... it was the IAC valve.  Turns out my original one was a rusty nasty mess... No doubt it was because I had the engine stream cleaned without covering the open throttle body.  Whoops

Then while trying to trouble shoot it, the throttle body I swapped on also had a bad IAC valve.

It idles like it should now.  Unfortunately, now I have a broken fan controller.  Unknown if it's related, but tonight we wired up the AC and charged the system.  Tonight was the first time the AC input to the fan controller ever got power.  A short time later, while working on other stuff, the motor was idling away.  I looked over and saw the temp gauge was pegged. 

I shut off the motor and inspected the radiator fan.  The fan or controller was emitting a high pitched frequency and the fan was not on.  Supplying power to the fan makes it run strong.  There's no sign of life at the controller though.

I'll call them tomorrow to see if they'll help me out.  I ordered it before the house burned down, so I'm a couple days passed their 90 day warranty.

Sorry, I was being sarcastic.  The house burned down nearly 2 years ago, and seriously delayed this project.

DC Control was really great to deal with today.  They answered my email promptly and through a dozen or so back and forth emails was able to determine it was my install that needed work, not their fan controller. 

When the unit gets delivered the studs have nuts already on them.  I used those to connect the electrical lugs, but that's not how it's designed to work.  Those nuts need to stay in place to hold the lid on the housing.  Put the electrical contacts on top of those nuts and use the additional provided hardware to secure them.

Pulled the top off today.  Put in 4wd for the first time today.   :D :D :D

I cut in some lights for the rear bumper.  On the front bumper I test fit the winch, welded on the brackets for a 20" LED bar, and welded all the plates on the All Pro bumper.  They only weld them enough to keep them in place.  Trouble is when you paint or powder coat, they won't get paint in the crack between the two pieces of steel, so you end up with rust in the crack.  So I welded the entire perimeter of all the plates on the bumper.  Both bumpers are going to the powder coater tomorrow. 

Tomorrow I plan to weld on the rock sliders.

Engine has been running great.  I need to hook it up to a scanner soon and make sure all my monitors have cleared.  Ref appointment is Friday.

I've also lowered the tires to 26 psi, then again to 24 psi, each time it handles noticeably better.   Contact patch seems to be full width now.

Ref appointment is Friday morning.  Still haven't gotten the EVAP monitor to complete.  Getting pretty nervous it won't happen in time.

You should be able to google the drive cycle.  Seems like it just needs a couple full temp cycles and a little freeway

" 2000 and newer model year gasoline powered vehicles will need all emission monitors in READY or COMPLETE status, with the exception of the EVAP monitor. An incomplete evaporative monitor will not cause a smog check failure. It will be the only monitor allowed to be incomplete on a 2000 & newer gasoline powered vehicle"

not sure you need it as stated in CA smog rules

Unfortunately it looks like that info is only for smog checks.  Referee inspections require all monitors to be set.  Jeff ran into this exact scenario before and the referee failed him for only an EVAP monitor that hadn't completed.

Tonight I used Jeff's scanner (a professional level scanner, not like my cheap one) and I was able to see I had a pending EVAP code that was not visible from my scanner.  You cannot get the EVAP monitor to complete with a pending code.  The service manual listed a dozen causes for this code, including vacuum leak, gas cap leak, bad VSV.  We smoke tested the system, but found no leaks.  I put a new gas cap on.  I also found that the VSV was not clicking when idling, like it was the other day.  I got an entirely different EVAP box with a different VSV on it and swapped that in tonight.

For the drive cycle, Toyota specifies the air temp and coolant temps must be within 13 degrees at start-up, so right now I'm waiting for the engine to cool.  Then off to try and get the monitor to set.  For a 2000 4Runner 3RZ it specifies, cold start, drive 45 mph for 5 minutes, then 25 mph for 15 minutes with at least 2 stops, minimum 30 seconds each. 

Since I had to lower my radiator, it was hanging out below the frame where it was vulnerable.  This weekend I built some protection for it.  I also welded on the rocker protection. 

Jeff used his forklift to flex the 4Runner tonight.  The rear tires were into the body pretty hard, preventing the rear tires from stuffing all the way.  I absolutely have to flare this fenders before hitting the trail.  Even with that issue, I was still very impressed.  The rear is going to flex great... the front is just ridiculous!   :D :D :D

Success!!!!!!!

Not sure exactly what it was since I threw a few different parts at it tonight, but it's fixed!  The monitor set quickly too, under 10 min.  I did the 45mph for 5 min, then 25 for about 3 min.  Came to a stop for 30 sec and decided to check the computer and it already showed the EVAP monitor had completed.

Flex zilla! Makes Me jealous and wish I linked Mine.
How are the high speed road manners? Especially high speed turns with bumps?
Makes it much worse that our trucks are the same color.  :shocking:

I was a bit nervous of it's on road handling characteristics when I first started driving it.  Now that I've got the tire pressure set so that entire width of the tire is on the pavement , it handles good.  High speed bumps and dips are no issue, it behaves just like any normal car would.  The suspension is very soft, so it leans out of turns quite a bit. You definitely have to keep a steady hand in the curves , especially at high-speed.  I took it out on some winding two lane roads in the hills for about an hour one evening this week. I felt very comfortable with it.

I got to see the rig in person tonight. As everyone knows, the fab work is spot on. The foresight and attention to detail is what sets this build apart.

See ya at MCR.

Thanks Greg.  Your truck is looking killer

Had a very stressful morning, but it ended well.  At my 1st ref appointment he told me to bring back documentation from Toyota that shows they have inspected my ECM and that it is up to date, and unmodified.  I visited my local dealer a few days ago.  The tech plugged in his laptop and ran a 'health check', which it passed.  He told me this is the only test the dealer is capable of running on this ECM.  He printed 3 pages that showed he had done a health check on a 2000 4Runner 2.7L 3RZFE, and that no issues were present.  It didn't show any type of serial numbers, vin, or revision numbers of software on the ECM.   

Today I showed up 15 min early for my appointment at the referee.  He immediately asked for the documentation from Toyota.  I gave him the 3 pages I got from Toyota.  He then asked for my invoice.  I told him there was no invoice.  I'm a long time customer at that dealership and they didn't create a work order for the 5 minutes of time I took to do the check.  The ref threw a fit.  I showed him his own paperwork where he specified for me to bring documentation that the ECU had been tested and that no where did it say I had to provide an invoice.  He told me my paperwork wasn't going to satisfy what he asked for and actually told me to leave and that I'd have to reschedule my appointment when I had the paperwork he wanted.

I protested, explaining how the Toyota Master Technician told me this was the only documentation he could provide regarding a test of the ECM and that there is no such thing as different versions of the software, so it is up to date.  He again said I would have to reschedule.  I pointed out to him that my appointment time didn't even start for 15 more minutes and told him I would phone Toyota and see if they could provide an invoice by email or fax that specifies no other software revisions exist.  I stepped out and called the dealership.

I was told again by my contact at the dealership, the documentation the ref is requesting doesn't exist, and unfortunately the tech that did the work isn't working today, so having him talk directly to the ref wasn't an option today.

I walked back in and found that the guy I had been dealing with had a mild change of attitude.  I suspect the other (more senior looking) employee in the office had tuned him up a bit while I was out of the room.  I relayed again that the documentation he's asking for doesn't exist.  Now he says, he's willing to do the inspection, and that he may have another way to verify the ECM is stock.

They start the inspection and don't say another word to me for 165 minutes... of my 90 minute appointment.  At one point I hear him in the garage getting really vocal about something being wrong and heard "because it's a not a 4x4."  I can only assume that was when he was physically looking at my ECM and saw that the Toyota sticker with part number, specifies its for a 4x2, M/T.  I heard the more senior guy tell him, "that's mechanical. It has nothing to do with it.  Just do your best."

Finally he comes in and tells me I've passed.  I asked for some clarification of what happened, so that I can better inform other people who are also doing this swap of how to be prepared for their referee appointments.  He says (with attitude), all anyone needs to know is in Appendix E of the CARB engine change guidelines.  Ok fine.  So I ask how he specifically verified that my ECU was not modified today.  He tells me (again with attitude) that I was very lucky I had brought the VIN for the vehicle my engine came out of, because he was able to get data from it's last SMOG check and verify that things matched up. 

I told him ok and thanked him for the info... but what a load of crap!  I pulled my engine out of a 4Runner with an auto tranny... so it had a different ECM.  This ECM came from a wrecking yard and we have no idea what the VIN is for that vehicle.

So... I won the battle.  I'll never have to see that guy again.  Yea for me. 

Got my BAR sticker and headed right over to DMV to get it registered... and to finally get my plates on it!   Now the referee stress is over... hopefully I can chill out and enjoy getting it ready for Rubithon!  Need to change the intake so I can mount my 2nd battery in the engine compartment, wire the 2nd battery, plumb the ARBs, wire the compressor, ARB solenoids, rock lights, light bar, back up lights... and flare those fenders!  I've got 2 weekends, so I think it shoudn't be an issue.

Got the freshly powder coated bumpers on last night
