I have an 87 pathfinder with 3.0v6 and MT. I am having an idle problem. Its surging back and forth from 1200-3000 rpm. If i press on the gas pedal at all, it goes to 3300rpm instantly. I unplugged the TPS sensor(or so i thought) and started it up and it idles steadily at 2900rpm without surging....but i guess it wasnt the tps as i could press on the gas and rev up the engine. Does anyone have any suggestions or have a diagram of the TPS so i know what i am unplugging/working on? thanks.

Your mass air flow sensor has died. Trust me. It's on the driver's side of the TBI.
