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.

(IMG:style_emoticons/default/smile.gif) did you check the throttle-body itself? do you have the right (thick) gaskets between the intakes and the heads? did you mount them with sealant? while the motor is idling, spray some brake cleaner around the suspected areas and see if your idle will change. but careful, brake cleaner IS flammeable ...
