The battery is Aug/2011. I didn't realize it was that old. It's still has strong cranking power. I don't really want to spend $100+ on a new battery if that's not the problem.

 

You can due a load test on the battery.

 

Take it in and have them test it while in the truck. Turn on your lights, radio, a/c, etc to get a good test.

I did take it and had the battery load tested. They said it tested fine. I did replace the air charge temp sensor that I cleaned with tb cleaner and later learned that I should have cleaned with brake cleaner. Nothing has changed with the idling and the lightning bolt is still coming on and going into "limp" mode. I did check for any new codes by turning the ignition switch on/off 3 times and it's not showing any codes now. Before it showed P0171, P2173 & P2106. I'm thinking about biting the bullet and ordering a new throttle body. I don't know what else to do. Anymore ideas/suggestions please?!
