2008 dodge charger 3.5L - 6v
My charger is misfiring #4 valve- I have replaced all spark plugs and coils. In the morning it runs fine. But if I run into a store for about 10 mins. and restart my car it starts to misfire again. It like when it gets warmed up that is when the car starts to misfire again. Please help......what is wrong with my car.....I don't trust the dealers....
