Default Throttle issues...

So driving along and let iff the gas and my rpms stayed up. The only way to get them to drop is to tap the gas pedal. Do you think its my 90mm tb getting stuck? Or is there something else i should take a better look at?

I'd scan it for what the throttle position sensor was seeing. If you don't have a scanner that can read that like HP Tuners I would take a guess of the throttle position sensor on the pedal.

Ok I will check that out. It seems like the pedal is getting stuck. Could be that it is hanging up from lack of a proper reading? Or do you think it's possible that the cable is somehow getting stuck? Sometimes if I get on it a little bit and then go to push the gas back in the pedal requires a little more effort like something isn't letting it move as freely as it should be. I don't know though. I will check that out first.

You do know there's a difference in years? You really should list your year with a question. It makes a difference

Did it just up & do it or did it start after a change?

Did it throw a code?

I would check IAC control along with TPS. MAP would be good to look at if you have logs of it running before it started doing it. It is a possibility it may have developed a intake leak somewhere.

Sounds like you have it in a bind somewhere.

Just randomly started. I checked iac didn't seem to be getting stuck. The tps seems fine to.

Remove the intake tube and the cable from the throttle body. Rotate the throttle and see if it hangs anywhere. If no hanging, then check the cable assy and make sure the bracket is not bent or the cable is not kinked or just needs lube.
