I have 2006 Jeep Grand Cherokee Laredo. About a week ago my check engine light came on. I took it to Advance Auto Parts and they hooked a computer up to it and said that it showed a cylinder 5 misfire. What should I do? It only misfires when I go up hill.
could be sparkplugs, wires ,rotor ect when was last tune up ,maybe vacume leaks,
