Re: Timing Problem
Matthew,
The timing won't be at 0 degrees with the bypass connected, but 20-30 degrees BTDC seems a little high to me. The noise under acceleration you describe sounds like timing knock or pinging to me. The ECM is supposed to retard the timing when the knock sensor senses pinging. Don't know if the distributor problem could have caused a problem in the knock sensor but I doubt it. If it is pinging you hear, it could be bad. My book says you can test the sensor by tapping the engine block with a metallic object (breaker bar?) with the engine running and the timing should retard. I've never tried this so I don't know if it works or how easy it would be to do. Good Luck, I hope you find the problem.
Rick
