Post subject:	cant fix CODE P0507
Hi Folks I cant fix the code P0507. (Idle Control System RPM Higher Than Expected) Checked in two repair shops, they checked IAC valve, Throttle Body, fixed a couple of Vaccum Leaks. But the check Engine with this code appears again. When Idle (Normal temp) in Drive the RPMs are about 650-700 RPMs, changinf to Neutral or Park changes the RPM to aprox 1000 RPM. I have several months trying to fix this. What else can be? Thanks in advance

You say the shop checked the IAC, was it ever replaced? Was the throttle stop screw moved at all?

I would replace the PCV valve and if that doesn't work try a new IAC.

Hi. Unfortunately the code was shown again. RPM on P or N are about 1100rpms. Could be the IAC? thanks
