my throttle likes to stick at about 2000 rpms but only when the car is running. it moves freely when the car is off, but when car is running it will get stuck. Any ideas?

 

happens all the time, especially just after cleaning. Lubricate it. The old/worn bushings have slop that allows easy movement when the engine is off, but engine vacuum bends the shaft a tad, and it binds the shaft and causes the sticking.
I was in a pinch and used WD40, and it's been working for months. Do a search for what is most recommended I guess.

 

i cleaned it a long time ago thiinkin that it was gummed up with carbon but never lubbed it afterwards. i then cleaned it again recently because i thought it was gummed up again but now it started to get worse and stick at higher rpms. i'll lube her up tonight (no pun intended) and seee how she drives. thanks alot.

 

well i lubed her up tonight and it didn't stick anymore. I'll prolly run a second return spring just for ensurance. thanks for the help.
