My other 2000 ranger 3.0 i had it from 64k miles, to 525k miles.....this 01 ranger I got it with 220k miles, it now has 325k miles....i have some exp w rangers, though not a mechanic per se....both trucks 3.0......i had noticed on the old truck that sometimes if i moved, touched, or jostled that taped area where the grouping of wires for IAC, TPS, DPFE,ECT etc come together, that the engine idle would change, usually going higher.....i never pinpointed the actual problem at that time but i did notice that the idle was always either normal, or around 200 rpm too high, ............it got to a point where if i noticed it high while at a stoplight, i could get out of the truck , nudge that grouping of wires and the idle would drop to normal.....jump a few years ahead to now, i noticed my current ranger doing the same thing, I said to myself i have to pinpoint which wire is causing this, and i did.....its the top wire on the TPS pigtail, a red and grey wire if I'm not mistaken....its a little dirty and my eyes aren't great but I'm pretty sure its red and grey......im gonna replace the pigtail but in the meantime , i pulled over into a parking lot when idle went high, opened hood, gently moved the red and grey wire a hair til the idle went normal, then i wedged the tiny sharp end of a toothpick into the hole on the back of the pigtail where that wire goes in so the wire / contact/connection cant move around......the high idle was happening when that contact/connection wasn't perfect.........since I've wedge the piece of toothpick into the wire hole to keep the wire still(not moving), the idle hasn't jumped up one time and the truck is running great......not sure what info is transmitted thru that wire, or to where, but that was 100% my problem, and if my two rangers had the same problem how many others have this issue and don't know it , hence my post......only extra thing to add is both trucks had pigtails that had broken clip on tabs to lock them in but they both fit on normal and well as many do with similar broken clip etc......BUT I often wonder if people damage them more pushing them on harder BCUZthey have the broken side clip .....
