I'd take it to a dealer to have the codes read/diagnosed and go from there. Sorry, I don't have any other suggestions.

Eric,

 

I would also recommend contacting your local dealer for a dignosis. Please feel free to keep me posted and contact me if you need any additional assistance. Thank you.

I would look for corrosion in the plug.
