Yeah, I drove my LX around for about 8 months before I tore it down. Ran fine with the A9P computer and a 5-speed. Not sure if the computer gives you a performance boost though, I never heard that. I think the idle control strategy is a little different to account for the weight of the torque convertor or something though...whatever it is, its insignificant at best. Like I said, drove mine 8 months with no idea it had the "wrong" computer.

How you tried pulling codes? First thing you should do. There are a few codes that can show up that report something wrong with the ECU itself. Also ignition components can cause what you are seeing. Earlier this year I dealt with a dist. pickup going bad, sometimes would cause the vehicle to not start after shut down until it cooled down for a bit. look for the "erractic PIP signal" fault. Tell tale sign its the dist. or TFI module.
