Hey guys as you can see i'm new but I have a problem with my buddies sunfire. His 2nd cylinder is misfiring. Ive checked and replaced the plugs and the wires and check for any damage on the cap and there was none. So the only other two options i can think of is either a bad injector or a bad head gasket. The car has about 150,000 miles on it. My first question is where can I find a service manual for the 1998 pontiac sunfire so i cant fin out where and how to replace the injector, and the second question is, is it common for the head gasket to go bad on these cars at 150, and cause a misfire?
