Finally received new unused idle control valve. The idle is now perfect 500 in gear, BUT the idle is 900 rpm in P or N. Have checked throttle switch and temp sensor. Control unit and valve are new. The funny thing is when I switch off the lights and heater the idle will raise to 950 rpm. What may cause that high idle??
