Driving home from work today I noticed that my engine was idling at about 2000 rpms. I checked the resistance of my IAC and the voltage to my IAC and they were both within specs. I cleaned it with carb cleaner and reinstalled it and was still idling high. I check the resistance of my throttle position sensor (TP) on the terminals which correspond to the brown/white and gray/white connector wires on the sensor and got an "infinite" or "open" reading. Does this mean my TP is bad and causing the high idle?
