    Miscellaneous/General Honda Ridgeline Discussions
    I have a 2006 Ridgeline with about 180,000 miles the check engine light came on for the first time.I had a full service tune up put on it spark plugs,air filter etc what could be the initial problem,never had the valves adjusted could that be a cause?
