    Default VS V6 engine misfire or cut out

    I gave my daughter a VS sedan(her first car) which we had from near new it has sort of a misfire but it’s not if you accelerate normal the engine does it however if you accelerate fairly hard to hard it goes fine . I have changed the spark plug leads and spark plugs. It idles well and when you’re at a constant speed its fine it’s just the acceleration part you could nearly call it jerks. Would low fuel pressure cause this?

    I doubt low fuel pressure....do a codes check although it sounds like one of the coils on it's way out. Checking error codes VR/VS (Revised)

    Definately sounds like one of the coils, at the start of exceleration its sluggish but then it picks up,I have had this same problem a few times,but your better off replacing all three of them if it turns out to be the coils because when one of them goes the others arent far behind.
