what could cause my car to misfire at sign light/signs and run hot?
I have had major issues with my radiator not flowing correctly, the car seems to misfire at stop signs and red lights. It has died on me many times. I've flushed the engine and radiator but there was white foam/bubbles coming out of the top of it while the car was running. The gauge inside the car never shows it running hot but when the hood is open you can feel the heat coming off of the engine. I've purchased a new thermostat, spark plugs, avc valve, new mass air flow sensor, and a radiator and water pump. what should I do??? Please help me...
