I have an 88 hatch- stock d15b2.
once the car warms up, the throttle has a habit of sticking and it starts revving after i take my foot of the pedal. I've PB blasted and white lightning greased the throttle cable near the pedal, near the carb and even the throttle on the carb.
i feel like it might be a simple fix but I can't figure it out..
could I get some suggestions?

 

any help?
this is annoying as ****
maybe it's the carb?

 

you might try and find a known good one swap it out if it fixes it you know what you need if not you know you can elimnate that. check the spring on the throttle bodie it might not be functioning properly causeing it to stay open or st..
