When I am driving and I switch gears, the RPM’s do not really want to drop down; I literally have to pull the gas pedal back with foot in order to get the RPM’s to fall.
On the rare occasion they do fall down it gets stuck around to 2k and once again I have to pull the gas pedal back with my foot. I thought maybe something on the throttle wheel was stuck so I sprayed some wd-40 on the throttle wheel and did not fix anything. Any ideas?


Also in the last two days I started experiencing something like a little hiccup around 2-3k. For example I will be driving coming onto a red light so I let off the gas but leave the car in gear and before I stop the light turns green, so back on the gas. at that moment when I press the gas the car "hiccups" almost like stutters and then goes no prob. what could that be??

Thanks for the help!!

Aftermarket throttle body or stock? Most of the billet aftermarket throttle bodies I have tried have had the sticking issue you are describing. The throttle plate wears into the billet and glues itself into place.

Maybe try another throttle body?

As for the hesitation problem, make sure your TPS is calibrated within spec so your ecu is reading closed @ 0% and wot @ 100%. Check you manual for proper voltage specs, I can't remember what they are off thetop of my head, somebody on here will though!

Thanks for the reply!

I will check the tps voltage!

With the throttle body, it is stock, so what your saying is that I should take it off, take it apart and polish the inside a bit to get rid of any grooves?

Thanks!
