ANOTHER 22re misfire...help!
Been chasing ghosts here for a month now. When starting my truck, it usually wont start unless you give it a little gas but when its cold it will most likely start right up. idk if thats got anything to do with my misfire....SO you can sit there and rev the heck out of it in neutral with very little to no misfire. It idles fine, but once you take off and accelerate a bit it stumbles pretty good. full throttle is little to no misfire. Ive done plugs, wires, cap, rotor, fuel filter, air filter, a bottle of fuel injector cleaner and i believe the guy before me did a fuel pump as well. Now i know the first post is gonna be about timing, i know, but im not fully convinced yet. Ive been sifting through all the misfire posts and cant seem to find one that matches up. Any ideas guys?

I am guessing you are talking about your 88. It probably has the old style injector connectors. While it is idling, try wiggling the injector conections. By misfire, I am understanding missing on 1 or more cylinders.
They can be brittle and look like they are connected to the injector and may even be on the injector, but it doesnt take much to break the connection.

It has a little wire like c-clip that holds it on to the injector. I said to wiggle but should of said to give a slight tug and push on the connector. May need to use a pair of needle nose pliers or something similar.
I had a problem of it running great and going down the road it would start to cut out. Guess the wind was pushing it off or if I floored it, the spark would jump the gap and run fine. That was my theory. Took me awhile to find it.

I have had the same problem. Check you O2 sensor heating circuit. If your O2 is not warming up and the ECU goes into closed loop it stumble and runs like crap. At full throttle you force the ECU back to open loop and it runs fine.

2 of the wires going to the O2 sensor are for heating it and 2 are for reading the sensor. Depending on the year and what has been done to the truck the colors will very. Just check your wiring to the O2 sensor for splices or burned wires.

Pretty sure my miss might not even be a miss as much as an "EFI" or "IGN" component that's just A TEENY bit off... Could even be my FPR or leaking CSI or something the like(had RC service my injectors 8K ago, with an "EXCELLENT" passing grade on all 5, including CSI... but NEVER KNOW, lol.) Still think it's a weird 'spot' in my AFM or IGN or fuel pressure issue... The hunt WILL continue, but I can only check EVERYTHING SO MANY TIMES, right? (Plus, my "MISS", if that's what it is, is more of a very slight erratic 'puppupup-pup-pup-pupupup' at Idle and low RPM once hitting closed loop temps.. So doesn't sound too similar, but still, can't hurt to mention everything that causes 'gremlin-drama', right? lol)
Sorry OP.. not trying to get answers for me... just sharing to show "I can relate", lol.
still watchin!

ok so its been forever but im back...and the misfire is still there. i had my 02 sensor unplugged aslo have my pcv valve unplugged with a bolt in the vacuum line...the truck ran great! the misfire was barely even there. once the truck warmed up it was gone. now i hooked up the o2 sensor and adjusted my timing (which was off a tiny bit) and the truck runs like CRAP! Im lost...misfires until 3500-4k rpm than runs great but it wont even hit rev limiter it just kinda sputters.

Have you checked your maf ? I have the 3vze and i had a similar problem. It was the maf connector was corroded and causing it to not send a strong signal to.my fuel pump. Now im not asking for sarcasm or anything else. Just maybe worth a shot.

Yeah cause that iac goes sometimes. It has to open wider when you shift from park or neutral to drive. Its not a real hard fix, not sure on price. Usually they can be cleaned but if its been in mud or water, its probably filthy!

IAC seems to be ok....idk what to do here...if i don't get this figured out my yotas gotta go its gotten to the point were the truck doesn't just misfire any more it just runs like a turd!!!!

Do you have any codes?
I had this same problem with my old 22re and i couldnt ever figure it out. Only thing id say check is coolant temp sensor and the TPS. After that maybe check your mechanical timing to see if your timing chain skipped.
Oh and i love my 3vze hehe
