The car failure related to EGR. My mechanic said car does not have EGR, model year too early. He put some injector cleaner in the car and suggested I drive the car 50 / 100 miles since I just received the car from Tennessee a week ago and then take for retest. Any ideas will be appreciated. Thank you. Mike.
