car way to old for any warranty. you need to go somewhere else for your diag. 2ooo and no answer???? you need a refund due to a bad tech. at our shop, the motor replacement is around 4ooo with a 3 yr 5oooo mile warranty. get your car out of there and to somewhere where they know what they are doing.

Only in a bad shop. Have them run computer codes, one or more of your ign coils is defective or you have a broken spark plug. Are you hearing a pulsating noise while the engine is running?

Make sure they check your variable timing, cam phaser out will cause all kinds of other codes and confuse bad Techs
