Throttle getting stuck slightly open Options

[ecaddiction]

Ok, here's whats going on. After using the gas pedal, when I disengage the clutch, sometimes my RPM's stay up anywhere from 1500 to 3500. If I just tap the pedal, it goes back down to normal idle speed. I figured my cable or something in the throttle body was getting worn out. With the car off, I went and messed with the throttle from inside the engine bay, and it was perfectly fine. With the engine on, I can feel the resistance. I sprayed WD40 on the TB, that did nothing. I checked to see if the cruise control was messing with it, and nope. So now I come to you 6gc. What's going on?

i've had that problem too... about a week ago it started to do that, would idle at 2k.. unless I tapped it then it'd go down.. so I checked the cable.. loosened it a little.. actually found out that nut that holds it together was stripped.. so i pulled it off and put on a new one..

but today it started doing it again.. so i'm thinking the cable is just a little too tight and can keep it from going to normal idle..

but if anyone else knows what is going on.. let us know!!

you guys try spraying carb cleaner into the throttle body with the intake hose off?

Well, my WD40 treatment helped, now it does it about half as much, and half as dramatic. I sprayed WD40 into the TB too, but not too much, because I didnt want to suck in to much wd40. I guess they're pretty much the same thing. But Jaws, definitately try spraying something in there. I'm hoping it will work through, and get better. *crosses fingers*

could be the part by the pedal thats stiff, road salt and water tracked in off your boots, old grease, or it could be a kink in the cable, a rusted cable, etc.

Yea, but the thing that confuses me about most of those theories is that the system is smooth when the engine is off.

I had the same problem on my car, but some carb cleaner/WD40 sprayed into the TB took care of it. Just make sure you clean the TB and intake valve really well (keep spraying and wiping with paper towels until the towels wipe clean). Over time, gook can build up on the intake valve and keep it from opening and closing smoothly, so you just gotta remove all the gook.

I was having a similar issue a while back. I would come to a stop and my pedal would stick, so I would have to slam on it to free it up.

I sprayed carb cleaner onto a rag and stuffed the rag into the TB and gave it a good cleaning. Never did it again.
