Hello there, I have a problem with my 300M, engine works perfectly but when drive above 75 miles there is a short glitch happening every 15-20 sec, when I lower speed below 75 miles everything fine, this is happening only when car pass speed of 75 miles or 3000 rpm, car was connected to the computer but is not showing any error, is it possible fuel pump?
