Hi
My 2013 challenger has gone in for it's 30k service (and cooling system recall) and the service center have advised me that it has a knock in the engine and proceeded to remove injectors for testing as they think one maybe be over-fueling and thus causing more combustion in one cylinder and therefore causing a knock.... Interested to know if any one else has had this issue and if it has been fixed. I thought the car was running better than ever before the service, it didn't use a drop of oil or coolant and pulled like a train.
Cheers
