Throttle body not working properly. Codes P2111, p2104 (if I remember correctly). This occured directly after replacing the battery. I'm assuming it has something to do with the circuit to the throttle body? Sound familiar to anybody?

 

i`m at work so i cant look up those codes. many tb problems can be resolved by cleaning the tb. have you done that yet? pull your intake tube and look inside. if its all black it needs to be cleaned ( should be shiny in there) you can also do a coolant bi-pss on the tb on the 05. its not needed and makes removing it alot easier to clean.

 

Thanks for the ideas. I just took the car to the shop- I gave up on it. (And I have no tools.) Issue was resolved though... turns out it was a faulty spring in the TB. It lost it's "springiness" so wasn't working properly.
