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.

Mike,
Thanks for the link. I do feel some hot air coming down from somewhere in the vicinity of the heads, but not sure if it's pulsing or steady. I have very little experience (OK, none at all) with exhaust systems. I'm a little lost on some of the terminology. It appears that there are 2 round tubes on either side that bolt up. I imagine these are the most likely locations of exhaust leaks. The ones more to the front of the car are pretty well shielded. Is it just a matter of removing engine tin up there to get at it? Am I missing something? Thanks. |
