OK here it goes. I have been trying to get this car running right for over a year now. When I start it, it runs rough and hesitates when I hit the gas. For a while it hardly ran at all but a friend of mine changed the fuel pump and that helped alot. Now it runs but I am left with this rough idle and hesitation when I step on the gas. I brought it to my mechanic and he changed the head gaskets. $1,000 later and the car did not run any better. I checked the plugs yesterday and they are black and smell like fuel. I am hopping someone here can help me because I'm stuck. Thanks for your time.
