My glorious check engine light came on...again. Before it came on and said I had a cylinder 6 misfire, so I replaced all of my spark plugs, wires, distributor cap, and rotor. It ran smoother for a couple of days, then the engine light came back on and it feels "laggy" or it hesitates when I drive. I have a bad clutch as well that I'm replacing on Sunday, but I'm trying to distinct the difference between my engine and clutch problems. I went to my local Oil Can Henry's today for them to plug in the diagnostic tester, and what do you know- cylinder 6 misfire again. I'm confused on what else can be done, or what my other problems could be. I obviously have a inline 6, 4.0L engine. Thanks in advance!
