Life of coil packs
My car has recently begun misfiring, so I replaced the spark plugs (broke 4 and had a blast getting them out), however the car is still misfiring. I eventually got a CEL saying cylinder 8 was misfiring. My car has 80,000 miles, is it possible that the coil packs should be replaced? Any other ideas on what could cause the misfire? Thanks, and any input is greatly appreciated.
