On my 98 Chevy Tahoe the check engine light came on so I went and had it diagnosed. The scan said that the #8 cylinder was misfiring. I changed the spark plugs, wires, cap, and rotor. The problem was resolved for about a week then it started acting up again. It would run rough at idle. Then another week later I was driving and it was running rough whenever I would accelerate and when I pulled to a stop light my druck died out on me. It wouldnt start after a few tries but when it finally started a real loud squealing sound came. It sounded lke it was coming from the alternator, but I could be wrong.
