96 4cyl Camry w/81k stalling at red lights and when at idle speed thru intersections. Had this problem about 2yrs ago and the dealer replaced the EGR valve, very expensive with labor and diagnostics etc..... Same symptoms now, the cars just stalls when stopped or coasting around intersections and so forth. I just replaced the EGR valve myself thinking it must be gone again, but the problem is still there. I plan to clean the throttle body plate as it looks pretty varnished up and also the IAC valve. Someone else mentioned their air filter looked pretty clean after 4 months. I replaced mine about a year ago (at least) and it looks pretty clean. This made me think that not much air is entering, though I can't say for sure. The car seems fine initially and tends to stall after its been running for a few minutes. I also heard a loud pop a few weeks ago, could have been a backfire, but I'm not sure. Funny thing is my friend was getting into my car with 2 balloons and we thought one had popped but that wasn't the case. What could cause a backfire? I don't mind bringing the car to the dealer, just don't want them throwing parts at it and eating up my time and money.
