This now has me completly puzzled. Check engine light went off and been running fine bc ive been letting it sit when going places. But had time today to look at it and tryied to get it to act up by doing short drives to random places leaving it sit then start back up and its been running fine cant get it to misfire at all. The only doffernce between today and the other day when it was misfiring is that the gas is a lot lower running with anout 20 miles to empty.
