Check engine light on. Code P0300. Replaced spark plugs, replaced air filter, replaced fuel filter. The coils were checked by disconnecting the electrical connection of each one and # 4 and #3 coil had no change in idle. Now code P1515 comes on. What does it mean if no change in idle and why the P1515 code? Runs rough and accelerates slow and gets very poor gas mileage. Please help
have the same problem?
