Been a great vehicle - no problems. Just hit 113,000 miles and it began idle rough and hesitating during acceleration. Had two engine diagnostics that found no issues. Dealer updated power train software, but didn't address problem. Thinking of having plugs and wires replaced as next step. Suggestions?
If the plugs and wires are original it would be good to have those replaced. Also on that vehicle it's a good idea to have the Mass Air Flow sensor cleaned during the tune up as well. -- LET FREEDOM RING
