OK, I'm once again stumped. My car just won't idle smoothly. It sounds like it's going to die, but then revs itself up a bit, then almost stalls again, then revs again... So, I thought it might be a vac leak. I had already replaced all of the hoses, but found that I had leaks on the air intake runner things, where they connect to the plennum. So, I disassembled everything, replaced those hose-type things, and voila! No more vac leak there. Problem is, still not idling right. It's just as bad now as before. One more thing, I slowly brought up the rpms from the throttle body, to listen, and I think I heard a couple of really quiet backfires. Maybe an exhaust leak? Could this cause a bad idle? Thanks.

Very good. It should be adjusted right. Be sure to leave some slack in the accelerator cable. You really need a CO meter to adjust it correctly, but you can get it close by ear. Turn the knob on the ecu ccw till it hunts, then back clockwise one click at a time till it evens out. If it doesn;t even out, then something is still not set right. Valves, dwell, timing, and tps must all be in sinc before the ecu knob will work as designed.
