this started happening to my car not long ago
and now i have a huge problem the car is misfiring. coil packs have just recently been changed too. perhaps my spark plugs are worn i will buy a new set this weekend and test this out. i will also put the old coil packs in one at a time to see if one of the new coils are gone. they are obviously still under warranty but who knows. in the meantime my car is running like complete shit. slow, shaking, sounds like a wrx too.
