I went and talked to the guy rebuilding my motor today. He thinks that I have a lean condition, and the cylinders are getting to hot causing pre ignition, and taking the bearings out. He asked me if the shop timed the car at 3000 rpm's. I told him no, since the only way I thought you could time a car was at idle? He said that if you time the car at idle and when you get your foot into it that the computer could be advancing off the board. He said usually by 3000 rpm's the computer is done advancing the timing and that is where you need to time it, and when it comes back down to idle you just have to live with what it is. Is there any truth to that?
