    Hello. New to forum. Looking for a person or service center in the southeastern PA, Lansdale, area that is familiar with working on the supercharged engines. Mine stumbles when under medium to heavy acceleration, going up hills. Has new coils, trans serviced. Under normal throttle input car drives fine. Worse when car is warmed up after driving for awhile. Want someone competent to look at my car, that knows these engines. Have had problems in the past and cars damaged by garages. Never had any problems with this car in the past. Run premium fuel but wife has been known to put regular in it. Thanks.

    No experience with shops in that area but this is likely something you can remedy yourself far less expensive than a shop if you have basic tools at home. Also, quit running 87 in it they don't like that.

    What year of the car and how many miles are on the spark plugs/wires?

    Welcome! I'm about a half hour north of you. What year GP do you have and miles? Like Ford man says. Don't run regular fuel, especially with these colder temps outside we are currently seeing. Minimum I can get away with is 89. If it isn't fuel then it's probably plugs, wires, clean throttle body. You know, normal maintenance things. If that stuff doesn't clear things up I can recommend you to my mechanic. He's not a specific 3800 shop (I don't think there really is such a thing) but he is very good and honest. DM me if you need more info.
