On a morning ride with the wife today, noticed the check engine light would come on, then a few seconds (maybe a minute) go off again. Did this several times during the hour or so ride. Retrieved the codes and got po152 (rear o2 sensor high) and p1353 (front cyl no combustion). No noticeable problems while riding or idleing. Any ideas before I make a trip to Wichita to the dealer?

 

Could be system relay... costs about $11.95 to find out.

 

Just a thought....

Do you have a Power Commander on it? I had that trouble with mine shortly after I put the PC V....I put dielectric grease on the 'inserts'.....havent had that problem since.
