89 740 GL starts and idles fine until warm.
Then idles speed +-750 rpm climbs to about 1400 rpm. Has new rotor and dist. New plug wires and iridium plugs. New fuel pressure control valve. New IAC, brake booster and maf. Runs great other than the fast idle and it's a little bit harder to start when warm... Engine temp sensor maybe? Any help appreciated. Thanks
