San Mateo, CA
My engine stalls and runs rough after driving on the highway. It will restart and run rough for a few seconds and than run fine. Distributor cap, rotor, fuel filter, air filter, pcv and sparks plugs less than 2000 miles since replacement. Spark plug wires 1 year old. I suspect it is the egr valve. I DO NOT have a check engine or service engine soon light on. Engine has 167,000 miles on it.
My service engine soon light is on. The vehicle is running great! I have checked the gas cap but nothing else. It came on after the late time I bought gas.
