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.

I got up under there, and made sure everything was tight where it bolts to the head. All seems good. I got back under with the car running, and I can't see, hear, or feel any leaks. My muffler is awfully loud though. I double checked my fuel pressure, and timing (both are fine) double checked for vac leak (nothing). I tried adjusting the ecu, it seems a little better when I went about 4 clicks ccw. Still not a nice steady idle. Any further thoughts???? I'm getting desperate.
