We are out on a 10 day trip right now and had some issues so just wanted to give others a heads up. We were going down the freeway and the check engine light starts blinking indicating a miss fire. Had to go an auto parts store to get the codes read and found out that cylinders 5 and 7 were misfiring. After a couple of hours I had the coils and spark plugs replaced. After examining the spark plugs, they were in BAD shape. I don't think the coils were bad, just the plugs. So I will do the other 6 plugs when I get home. Doesn't look like the plugs had been changed ever so thought I would give everyone a heads up to change your plugs if you have a high mileage rental RV!
