got my rig all back together, no coolant leaks today, and Ive been testing driving it today. So Ive had this same problem now really for years, but never have really addressed it. So my truck idles fine upon start up, but when I give it gas and then lightly let off the accelerator the accelerator stays partially depressed, or something causes the idle to stay at around 1500 or higher. To make the idle go back down I have to give a quick tap on the gas an then it goes right back down to normal. It happens while driving too,. So Im wondering if it may be my tps or perhaps I need to grease up my throttle cable? or maybe if I dont give a qick tap my throttle plate isnt closing al the way? anybody have these symptoms? is this indicative of the tps being screwed. One thing Ive noticed is that if my tps comes unplugge while the truck is running it will make the idle jump really high, and then when i plug it back in it goes back down. So my tps should be working, but maybe isnt adjusted. Any help is really appreciated.
