I tried posting on the boost forum... It has nothing to do with the boost anymore.
Quote:
I have a 96 sunfire and swapped to a 2001 2200 and also a 2000 4speed automatic transmission.
First round of the swap: I had the 2200 and the 96 3spd transmission. I used a 98 5speed pcm and 99 wiring harness at the time. ran fine untill the torque converter bolts snapped off... ran at 5psi of boost with 310cc low impedence injectors. ...Until the transmission blew.
Second round of the swap: I slapped on a 2000 4speed transmission with low km's onto the 2200. still with the 98 pcm, same injectors and wiring... no matter what fuel pressure it is (30psi 45 psi or 60psi) the engine will bog when warm. I changed the injectors back to stock(low impedence, top feed) only 1 time after the injector swap I was able to make a little boost before getting too lean untill it sounds like a machine gun, detonating. I had D.T.C .with the EGR. and dtc p0480(I don't have a fan right now so I pulled the out relay. I was thinking the E.G.R. D.T.C.'s sent the car into limp mode. also when I touch the throttle just a tad it pushes from the ?AIC and it gives it throttle until a couple seconds after stepping off. I also had problems with overheating while driving.
Third round: I replaced my thermostat, intalled my pcm, waited out the theftlock, started the car, cleared the dtc's, checked the injector clips. then I noticed something wierd... I turned down the fuel pressure then I saw sparks coming from the spark plugs hitting the head then died. I rechecked the plug wires greased the contacts on the spark plugs. Now if I just put a tad of throttle the car chokes and stalls or running exactly like limp mode.. I was thinking maybe I should replace my T.P.S.
Any help?
Today I replaced the throttlebody with a 56mm, map sensor, spark plugs and sparkplug wires, checked all the connections to the engine again (r&r)
I checked for codes again and hooked up a fan drove the car as long as i could stand and still no engine light. It's just ridiculous. nice clean idle... it just doesn't seem to sense the throttle position.

Found the problem! lol
the injectors I had were high impedence.... I was told they were low impedence because they were from a 3.1 Litre turbo.
I tested all the wires with my ohm metre for consistancy... and got me no where. checked the tps and that was working fine... 98x(0 throttle) - 16xx(100%throttle) and the other pin that gives the opposite. I hope after all that clipping, the injectors would still work. I'm going to grab a set of q4 h.o. injectors. so hopefully it'll work.
It works! It's running lean though. YAY ..................................me........

You shouldn't have problems running high-Z injectors on any ECU, it's low-Z on a high-Z ECU you need to worry about...maybe the injectors were just bad?
fortune cookie say: better a delay than a disaster
The high impedence 310cc injectors were working for a little while... they just died and gave me alot of headaches trying to figure out the problem. after a while it was just clipping on a touch of throttle. idle was fine though. good thing I was probing whatever made sense.
