Thank for the information. I will try that. Do you have any shop recommendations in the MD. area foror independent shops. I have a Check engine issue with a higher the normal idle PO 0507 that the dealer can't seem to fix. They want $1400.00 to replace throttle body for START and then recheck from there. What a joke. Another shop told me it was caused by using having Champion plugs. Changed to NGK and no difference was expected or resolved. Car runs fine and has no idle issue other then the annoying check light.
