We're going to replace it one last time today, reset the ECU properly, and I think I'm going to buy a new cap also. I really have no clue on how to fix it, I've tried replacing it a million times. We've timed it, did a full tune-up, replaced rotor,cap, plugs, wires. Nobody I've talked to knows what to do, even though a few people have had the same problem.
Some guy I talked to said it was the crank angle sensor in the distributor. It made his car idle REALLY low and his car cutoff at 3-4k RPMs, instead of going to the redline. I've had that same problem with one of my distributors. With the one I have on now, the check engine light is on, it idles low, but I can take it all the way up through 8000 RPMS. He says its the crank angle sensor that makes your car idle low, and he replaced his by taking two distributor housings, and taking the parts out of both to make one good one.
Hey, the other distributor he used to swap out the parts, was it the same obd version gsr dist. also? I'm having the same problem. My car wont go pass 3500
checked my ecu and it threw the code #4 which is the crankshaft position sensor.
