DTC P0508 is; Idle Air Control Circuit Low. Which means the Idle Air Control Circuit input is below acceptable limits. test the Idle Air Control (IAC) valve, the wiring between the IAC and the PCM and made sure the IAC passages in the throttle body are clean. If thats all good then the PCM probably needs to be replaced.
