Hello all. I tried to get an account on v6z24.com but they turned me down. Hopefully you guys can help me. I have a 3400 swapped into a 92 cavalier that is giving me a few problems. Going into the swap I never got to hear the Cavalier run or drive it. Oh how I wish I had insisted on this. But it had a blown head gasket and had been sitting for a couple years. Never again will I make this mistake. Anyway here's a list of the problems.
Lessor problems.
1)
Speedometer thinks I'm going far faster then I really am. I can hit the peg in second gear. By the rate my odometer goes at 70mph it thinks I'm going roughly 400mph.
2)
Oil pressure is constantly pegged while running - I believe I need to use the 3.1 oil sensor, right now I'm running on the 3400's.
Main problems.
1)
Sometimes the car will die when the load is taken off the motor. It will also sometimes die if a load is applied while at idle.
For instance if I have to stop suddenly and push the clutch in it will die. If I'm maneuvering in a parking lot and pull into a parking spot at low speed. The load from the power steering pump is enough to kill it.
Sometimes the IAC will attempt to control the dieing. With the rpms shooting up to 2k+ then falling back to 500. Only to shoot up again several times before settling in around 1k. Other times it will die with no attempt to self correct.
2)
Once in closed loop the car loses a large amount of power at roughly 3200 rpm. It is like hitting a wall, but only in closed loop. If the car is in open loop it will run strongly up to 5500 rpm.
3)
I have yet to measure it as my odometer doesn't work, but my fuel mileage is awful. I believe I'm getting less then 20 on the highway.
Stuff I know.
The car is running the WOT-Tech chip. All sensors looked good on a snap-on mt2500 scanner. I didn't have too long to play with it as I had to leave. I haven't been back home to hook it back up. I have not scanned it while driving and hitting the 3200 wall. There are no check engine codes.
