Engine Mechanical problem
1998 Toyota Camry 4 cyl Front Wheel Drive Automatic 134000 miles
engine stalls when waiting for redlight. So we replaced the IAC (new one from dealer), it worked for a few days then stalls again, seemingly at random.
Then the local mechanic replaced the fuel filter and fuel pump (new) because the pressure was not up to par.
Then after a few days the engine stalls again. The symptom is always engine behaves perfectly when driving, but stall occured when the car is stopping. Usually the engine just plainly stalls, but a few times the rev will increase to 1500-2000rpm, hang at that range for 30 sec, then rpm dropped and the engine stalled.
Twice, the engine stalls when I engage the AC, but I can always restart the engine afterwards. And the AC compressor appears normal with good cold air and no abnormal noise. But after this two time stall, it did not stall again regardless how often I cycle AC on and off within the next 30 minutes.
I am puzzled.
Thanks in advance.
