Here's one for the Braintrust:
I have experienced the same hesitation under 3k RPM as some other threads discuss. The car feels like it's' running lean and rough until I give it more gas and then the power will pop back in. The problem only happens between 1k and 3k RPM. My coil pack check was strange, I got a 1.4 reading on every pack, front and back. Even though this is above spec, the consistency of the readings suggest to me that there is no one bad coil, or that my meter was off. I removed some of the rust from the rear packs, applied electrical grease and put the car back together, but this did not solve my problem.
I'm reading that some people have solved this problem by replacing the O2 sensors, so maybe this is my next move. But there is one other symptom:
Every couple of weeks I will try to start the car and it will not fire. I will crank a few times, waiting 30 seconds, and try again. Every time this has happened I have eventually been able to start the car. It happens in warm and cool weather, when the car has been recently driven and when it has sat overnight. The frequency of this failed start is increasing slightly.
I wonder if these problems are related? I have Comptech headers and exhaust, otherwise stock. '92 70k miles.
Thanks for any insight,
jamie
