help on problem with ls1, engine dies after 1 min of driving first i want to say i'm about to switch to carb because this is making me really **** and i've wasted so much time on this project NOT to mention money.
this is a complete stand along wiring now, I have a 00ls1 and 00 wiring harness off camaro. the engine and wiring does no longer have any o2 sensors,air injection bypass valve, all auto wiring, egr system, all evap wiring and system.
I have cut off and out everything I did not need. everything is also turned off on the computer, vts is also turned off as well. I am running a th400
the problem is that when i'm just starting it up on a cold start, it idle perfect and have all 8 cylinders working and my datalogging be great, i can rev it as much as i want and it can stay rev up as long as i want without having any problems, as soon as i try to drive it out into the street, the car falls on it's face and the engine will start to cut off cylinders one by one untill i have like two cylinders left. then it will die, I can try to start it back up but then it will be very hard to start again after that, meaning it will just turn over and act like its trying to catch but it wont really stay running under it's power, id have to hold the key on start. all my 02 are turned off and i'm also in closed loop mode as well, so the engine can never go into open loop and relay on the 02's. i'm at the point where ive try everything. all different sensors and stuff. maf, map, iat, cam sensor, crank sensor etc. if i let the engine cool down I can then start it back up and it will start all over again.
help me fix my problem............THANK YOU FOR READING THIS LONG THREAD
