Re: Misfire problem
First thing to check is the spark plug and spark plug wire. A bad/damaged or loose spark wire can cause a misfire. When was the last time they were changed?

Re: Misfire problem
The auto parts scanner told me cylinder 3 misfire as well, but it was the number 6 wire that was broken. Check all your wires and plugs first.
