I recently have been having the high idle issue. Come to find out, the FPR hose was not connected to the resonator. I connected the FPR hose to the resonator and disconnected/connected the throttle body plug. The high idle issue was solved and the check engine light disappeared. I decided to run a scan to see if there were any pending codes. There were two permanent codes related to the TPS, P0122 & P0223. I am concerned that I nuked the TPS because I did not disconnect the battery.
