Question Details

Hi. We have an Cl55 amp miss firing between 1500 and 2000rpm.



We have changed the plugs and checked all the coils. The problem only occurs as the car warms up and steadily gets worse. There are no error code

Usually those problems are casued by fuel related issues. Flow fuel pressure or bad injector would be my guess.
