2002 SL2
Default Iacv fixed high idle now getting periodic low idle

Hi all once in a while my idle will drop to the point where the car won't idle I'll have to keep my foot on the gas or sometimes I can turn the air on and that will be enough to keep the car running then a few minutes or so the car will return to eight hundred or so. Also my car will ping if I accelerate hard but if I really flog it it will run fine for a little while and you can smell the cat.. I tried cleaning the egr valve but i have to say the little valve looked like it was toast could these all be an egr? Also the other day when I was clearing a high idle code due to iacv I noticed a code that was still in the works for the rear o2... Thanks!

REWARD EXCELLENCE!

Sounds like to me like a new cat may be in your future maybe? (Good luck with that in CA btw!) When it's doing that pull the front O2 sensor and see if it improves.
