Question Asked: Engine Stalls
October 09, 2010, 01:34 PM
The engine of my car stalls at various phases. After I start, the engine stalls sometimes. When I change gear, the car stalls sometimes. The most commom stall I have come to notice in the last days is when coming to a full stop. At the beginning I thought it was due to LOW RPM, but today when I was driving it, it idle really well. When I started to put gas (accelerate), the car would hesitate. If I let go of the gas pedal, the car would stall. Sometime when going about 45MPH, I can feel the car hesitating to maintain RPM. The mechanic could not find the problem. I change spark plugs, air filter, fuel filter, clean the throttle valve. The mechanic checked the oxygen sensors, and other sensors, including fuel pressure, and never found the problem. Please help, thanks!
