Hello,
My Saturn idles around 2500rpms. Once in gear it drops down to 1100rpms and seems to run fine. I've changed the plugs and wires. I had a vacuum leak at the PCV valve. replaced the valve and the hose. Also replaced the hose from the air intake to the valve cover. I've cleaned the throttle body a couple of times with carb cleaner. Found lots of grime. The first couple of times the idle did go down but went back up later and now is not affected. I can take off the PCV valve and the RPMs go up. Any ideas. All I get from the ECM is trouble code P0507.
Thanks,
