Engine Performance problem
1995 Saturn SW2 4 cyl Front Wheel Drive Automatic 150000 miles
my car started to run rough the other day. So I thought it was the spark plugs and wires so I changed them. But I knowest that their was some gas coming around the manifold a little out of one of the cylinder. The third cylinder from the passager side to the right. Was. It is flooding out and the spark plug is not burning the gas.. What I want to know what is causing this and how to fix it thanks. Oh yea I just had the head done because it had a burned exhaust value. But since then I knowest that the heat light comes on now and then but it never over heats.
