Glad to be aboard. Having problems with my Aspen and hope to receive advice on here regarding getting it fixed.

 

I have a 2009 Chrysler Aspen with 40,000 miles on it. No previous problems. Now getting the engine light on. When the light goes on the gas mileage drops on the gauge from 12-16 to 4-5 mpg. Dealer has changed out the Runner valve. worked for a while then light came on again. STAR got involved and recommended a new PCM which was installed. Again worked for a while but now the light is on again. Anyone have any similiar problem? Any suggestions who I might be able to contact to get help? By the way the code is p2016. The next recommendation from the dealer is to replace the vehicle wiring. Getting too expensive but don't know what the alternative is. HELP?
