I will ask if they can do a software update...
would it also fix my rough idle? like it feels like a misfire but it isn't one... NO CEL..
Apparently the service history said plugs were changed before I bought the car.. I don't know what else could be the issue..
every cold start as the revs come down it shakes like a mis fire.... also when letting the brake pedal go off a red light you also feel the same vibration
would a jb4 help me fix these problems?
