Hi everyone,
my girlfriend recently got a 230k mile 2007 liberty. It was driving okay-ish with a P0303 code until I replaced the spark plugs and ignition coils, which seemed to resurrect the car. It drives great now, however, it seems to be throwing a P0507 code now (high idle RPMS) and I can't seem to troubleshoot the underlying cause. For starters, the idling RPMs seem normal around 650 with little fluctuations. I can't find anything concerning a vacuum leak anywhere nor do I believe there's a problem with the throttle body, PCV valve or IAC valve.
Could it just be the computer needs to undergo a relearn procedure? If so, am I able to do that without a fancy OBDII scanner? Or do let me know if there's anywhere else I should check during this troubleshooting process?
Thank you in advance.
