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.

How do I test to see how much vacuum I'm pulling at idle? Is testing the mps the same? Also, the muffler is really loud at idle. When the car accelerates, it quiets down, and seems to run well. When I turned the ecu cw, it seemed to make the idle worse. ie. the searching more pronounced. I will go try pulling the wires. Thanks for the suggestions Mike.
