OK just got the motor back in the car and Im having a similar problem as last year...
Some times it fruns fine, idles fine, drives fine, etc... Its not hot/cold dependent eather, nor is it a open/closed loop problem.
Other times, it just sucks. It cant stay runnign at an idle, the rpms just jump from about 400-800 until it stalls. It canjt stay running in neutral, or at a stop sigsn, light, etc... for the same problem. I was thinking it may be a tps problem, but could that be intermittent like this? (I never slotted it for my BBK 58mm TB, but the car ran fine for 6+ months) What about the pcm?
Any suggestions are welcome, I just want to be able to drive my car.
Its a 385 stroker, BBK 58mm TB, new MAP sensor, aftermarket MAF ends, relocated IAT, K&N FIPK.
