2 months in, still not running right, this is what you should do, not buying another cam.The stock cam will remove any "cam cause" from your running issues, and allow you to focus on other possible causes if your running issues remain. You will also have a "stock" cam w/rebuild/other mods seat of the pants experience to compare with the other cams.
Then again, it was a 22R-E and an old 22R that were in Moab if that has any bearing on this discussion about which engine is the best...Maybe when Gnarls has his 2nd or 3rd midlife crisis he will springs for a V6 Camaro or Mustang and then get some bolt-on upgrades for performance...
Gnarls,Just to recap where you are at with this, you are happy with off-idle performance, is that correct? The main problems are bad cold starts, a high idle that does not work, and then idling too high after it is warmed up?Did you ever block off the EGR? If that leaks slightly you'll have all sorts of idle problems. Adjust TPS? Get timing back to stock? Get number 1 and 8 valves adjusted correctly?Another couple hundred miles on mine and I am very happy. I seem to be getting more power. The 261 may not have the idle power band for you but it seems unlikely that it is the cause of your problems.I do agree with a post a while back that the 261 likes a little higher idle. I have mine set around 900. At 750 it is a bit rough and does a little of the random blub-blub thing, like it wants to miss but not quite that bad.
Gnarls, I'm just giving you a hard time. I appreciate your willingness to share your frustrations with us. I think most of us have gone through this in one way or the other we're just not so brave to let the wolves gnaw on us. I also ended up putting the stock cam back in my 22re build and it did solve some of the rough running issues I was experiencing. I feel we have a lot in common as I'm considered an eccentric(and a smart ass) by most who know me. I like to keep an eye on this thread, it's like someone is ghost writing my 22re build story.
Arnt you running engnbldr's rv head? when I was considering going that route Tod told me that I couldnt run a stock cam with the RV head ( I wanted to know if going back to stock was an option if I didnt like the aftermarket cam). I dont know why it wouldnt work but if your planning to give it a try you might ask him about it first. The symptoms andykrow just mentioned, if thats what your experiencing it sounds like classic IAC valve symptoms. I think you have already been through that but thats what it sound like to me.Good luck, and keep after it
classic IAC valve symptoms.
Hey Mudder,Can I assume that you have checked out other possible causes for your engine to "fall flat on its face" at around 4500 and 5000 RPMs? Or.. are you convinced its the 261C cam?Have you talked to Tod or Ted at engbldr?How many miles on your rebuild?Are you planning to change the cam?Thanks,Gnarls.
Injector pigtail connector on #1 injector had to be replaced.
It's now got a loud squeal when I cold start it!!!!!! I think its a v-belt (the belts are tight, but I will recheck), and sounds like a pulley, alternator, or A/C pump pulley is not spinning at start up??? It goes away after about 2 or 3 seconds after it fires.
Gnarly,So what's the thread size on that banjo bolt for the fuel pressure tester?
I have similar experiences even with a carb 22r. I almost always get my best fuel economy pulling 4th of July and Lookout Pass when I head to the coast and back.
....I need a better radio!
I didn't install the 252, the truck had it when I bought it. Judging by your spreadsheet though I would have seriously considered it in my build. I went with the 261 mainly for price, but with all the money this ended up costing an extra 100 would not phase me at all, haha.
I am looking forward to your impressions when your motor is sorted out!
My fuel pump damper (on front of fuel rail) is leaking and I found this in researching it........https://www.motor.com/magazinepdfs/012004_08.pdfThe third paragraph on page 2 (article is pages 8-9, so it's also page 9) sounds vaguely familiar (if this is the correct thread)
In 89, Toyota got rid of the damper on 22REs.It seems it's possible to replace the damper with a banjo bolt. Search '22RE damper delete'I figured that mine lasted 31 years, so I just ordered one online from pepboys, will pickup this evening. There's currently a 20% discount coupon if you order online and pickup at store (probably 20% if you order online and have it shipped too). BTW, just had to remove the intake tube to get to the damper with a wrench and push the wire for #1 injector out of the way. The strange thing was that the injector rotated when I move the wire. I would think the injector would be stuck in place after 31 years and 174k miles........
