Thanks for the advice. But I think most of the people who look at sites like this are probably not just average vehicle owners. Myself I am a licensed electrician for residential and commercial spent many years as a maintenance tech troubleshooting high speed equipment with plc's and computers. So I think I can handle a little vehicle troubleshooting. But I do agree with you in terms of not just through parts at it. That can cost me more than taking it to the dealer also.

and you need a diagnostic trouble tree for the code thru any number of online service information,alldata is cheap enough and works good
