sr20det experienced help plz....

at this point you should really do a compression test. You could be beating yourself up for no reason. A ring or two could have been swamped with enough fuel when it was running like poo that you damaged them...

then check the maf's, and replace all coilpacks with known good ones from a buddy. If you cant get a complete set, just try to get one, and replace it one by one with each of yours to see if that changes anything.

I dont think your issue is the harness, unless you blatantly mismatched the wires, or missed some to repair.

Could be mafs, so its not bad to check that.

Could also be your injector seals. They are super cheap and easy to replace. You cant tell they are damaged, and will make your car run like assss. I would lean towards this before servicing your injectors. You pulled them and tested them, so we know they arent stuck open or leaking FUEL. These seals leak air into the system and fuck shit up.

Shouldnt be your temp sensor because you should be able to unplug that thing and get the engine to atleast run smooth...

Like I said, if its running on two cylinders, isolate the 2 that are not firing and figure out why. You said you have spark, ok. No fuel leaks, ok. Are the injectors even pulsing? Did you check for continuity to the ecu? It could be low comp like YucA said.
 
all cylinders r fireing.....for sure...checked with spark plugs on each coilpack...
ive checked alll coilpacks...spark and voltage..and resistance....
changed ignitor...no difference...
checked fuel pump voltage....
checked injectors for leaking injector o rings...by taking rail out and turning on...ignition..
for sure no leaks.....
im down to bad coolant temp sensor....
bad maf.....or bad ecu.....i mean wat else would make the injectors b stuck open and not thro any codes at all.....
if anyones willing to help plesae your input is welcome.....
 
When I say firing, i mean combustion. Like fuel, air, and spark - not just spark. I was under the impression it was only 2cyl acting that way. Once again, if you isolate the two, you can trace your problem back to the injectors if you know for sure you're getting spark and your plugs are good and gapped properly. If the injectors are stuck open, maybe there's a problem w/ the injectors.
 
so the injectors can be messed up and not throw a code?
i meant that it sounds like its runnin on 2 cyl....
it like in a limp mode...like i have a leaky injector o-ring with out having bad o-ring...
when it runs it idles bad and it revs up to 4 grand and starts breakin up....
just dumping fuel..

wat other seal r there other then the o-rings on the injectors...
the
o-rings r not leaking i pulled the rail off w pump on...
the engine ran worse when i pulled maf plug...
i checked resistance on injectors there good..
im stuck wit this i was gunna change ecu..
but everones taxing for the ecu

so if the resistance on the injectors r in spec...would that mean there not stuck open? and its the ecu?

im done

yes i got it fixed......
it was the swicthed power to the iacv....
when the wires rubbed in the wheel well it killed the switched power to the iacv..my driftbomb is back
