I need help finding the cause of OBD code P0507 Idle RPM higher than expected. I have replaced the Idle Control Valve and do not get the message on the highway only on short trips. I have also replaced some of the convient vacum lines. The vehicle seems to idle a bit high. can any of you more experienced than I help me with this

Thanks

Check for a vacuum leak causing the higher idle.

I will check for vacum leaks today. I changed the Throttle Control Sensor yesterday it seemed that the throttle washigh when stopping I am going to drive it today to see if that helped.
Thanks I will let you know how it worked

Besides the vacuum hoses, also check for a leak at the upper plenium gasket. Make sure the the hose going to the air inlet duct behind the throttle body is connected.

Iwill look into the plenium an dget back thank you
