Topic: Help Diagnose 22re Issue

[guywithuglyyota]

Hey Guys, Well I have a strange Problem with my 94 Toy 22RE.

A few weeks ago I was driving along and the engine cut out completely, but it was only momentarily, as if it were starved for fuel.

The problem did not kick off a fault code and I just assumed it was water in the fuel Tank.

The other night I was up wheelin, really flogging the engine in the upper RPM's and the truck simply stopped Idling, then threw a fault. I Jumpered the diagnostic port and it gave me fault code 12, and 14. And If I rememebr correctly that is the ECU or something is not talking to the distributor.

I unplugged the battery to reset the fault code, then I messed with the flapper door on the airbox with the ignition on. You could hear the fuel pump relay kick on, and the ECU relays turn on, then the truck ran as if nothing happenned for a few more days.

Then last night she did the same exact thing, drove great all day, then just stopped Idling out of the blue and threw the code. I tried same trick again messing with the air flow meter by the airbox and it ran fine again, with a slight stummbling initially.

Soooooooo....... Do you guys think it may be something as simple as a clogged fuel filter? Or perhaps Water in the Gas tank?   The problem is so out of the blue I cant see it being the ECU. But It may be Ignition related, like the Coil, distributor etc..... But I hear those things dont just go out.

I was snow wheelin and you can eat off of the Engine, so Im ruling out a bad/dirty connection someplace.

Thanks in Advance and sorry for the  Long explaination!

i know that my ignitor jsut went out one day, no prior warning at all... not saying thats your problem, but things can just go out without warning... might be a simple ground problem, too even.....

Thats what I was thinking...if you have a ground wire that has opened up it could just be catching a peice of metal and shorting out every once in a while.  I would start my search on the ground wires, then move to looking for any other wires that are stripped or damaged.  Simple things first, then worry about the big things.

re-ground your coil

Ok so I did changed the dist cap. rotor plug wires and plugs hoping it would be the dist cap or rotor.....

I drove for an entire week without any issues at all.  So my next question is what are the symptoms of a plugged fuel filter?

I was driving up the highway and the engine would cut out completely, but very briefly as if starved for fuel... Then at a few stoplights she would just die, then check engine light would come on. Im going to change the fuel filter tomorrow but I really hate shotgun maintenance like that even though it is due for a change anyway.

Im also gonna swap in a different Air flow sensor to see if that fixes it.  This is the strangest problem I have ever seen So intermeittent so its hard to say if you have fixed anything at all.

I will try re-grounding the coil as well, thanks for the help guys!

It may also be your O2 sensor. Sometimes your PCM will test your O2 sensor by either richening the mixture or leaning it out to see what readings it gets. If you have an extra you may swap it on there. Also, Alaska gas can get pretty crappy in the winter so throw a bottle of HEET in there every other tank of gas.
