you might want to check your egr valve. if it's stuck open and leaky just a little bit it will almost kill the engine. it's easy to check if you have a vacuum pump. they are cheap and available at any auto parts store. the procedure is in the chiltons manual. if you need more detail just yell. I'm having a similar problem. my idle is going up and down randomly. i'v checked every sensor that i can and everything checks out good. while testing the idle air control valve i found it was making the idle change but it was because its signal voltage was changing. the only thing i haven't changed is the pcm. any ideas?
Reset error codes, Oxygen sensor is ignored if old errors are not cleared.
The idle going up and down, depending upon how erratic, may be normal behavior during the warm-up process. Check the timing belt and make sure that the timing marks are still in alignment. Unfortunately checking the timing mark on the crankshaft requires removing the damper. Otherwise it'd be cake.
Could be MAF (Mass Air Flow) sensor. Located between air cleaner box and throttle body. I was having the same problem I unplugged the MAF sensor and it ran better. So, I replaced it and it ran even better yet. I replaced the fuel pump and fuel filter before that. But, it still ran rough. I tested fuel pressure and it was fine.

Where is the throttle positioning sensor on a 1988 accord?
Throttle position sensor is located on the side of the throttle body-in line with the throttle shaft. To locate the throttle body, you can have someone repeatedly push the accellerator pedal (with the engine not running) while you look for the moving throttle shaft. Drew

What would cause a good running 95 S10 22L to run rough sometimes but run perfict at other times?

Is it legal to pass to the running back and then the running back passes to a wide receiver?
Only one forward pass is allowed per play where there is no limit to the number of lateral passes per play (a lateral pass being one that travels parallel or backwards to the line of scrimmage). If the pass to the running back is a lateral pass, the running back is allowed to throw a forward pass to the receiver. If the pass to the running back is a forward pass, the running back is not allowed to throw a forward pass to the receiver.
