RPM sticking at 2-3k

2005 Aero Manual. When driving on city streets, stop and go, my rpm will get stuck at 2-3000 in neutral and first. Gets bad in rush hour traffic. I've cleaned the throttle body, replaced throttle cable, and cleaned the idle air controller on throttle body. Issue still remains. It will cause the clutch to smell if I get stuck in traffic for too long. I think the throttle cable linkage (whatever it is called) where the cable connects to the throttle body is sticking slightly. My next plan is replacing the entire throttle body and cable linkage. Anyone ever run into this issue before? Any help and information is greatly appreciated. Sorry for long rambling post.

Re: RPM sticking at 2-3k

I had this same problem a few years ago and I was able to fix it by giving some slack to the cruise control cable (right next to the throttle cable). Might be worth trying that before replacing anything else, if you haven't already tried it! Just shift the two nuts to release some tension:

Re: RPM sticking at 2-3k

I will try that next. Having other issues now as well with some vacuum loss somewhere. Thanks for the information!

Re: RPM sticking at 2-3k

Did we just become best friends?

Seems to have done the trick. I'll give it a few more days to see if it happens again but it feels better already. Thanks a lot! I've been trying to figure this out forever and turns out to be the simplest thing ever of course. I'm now back to loving my car again and probably won't sell it now!

Re: RPM sticking at 2-3k

Also, make sure to use your cruise control regularly... use the actual cruise functions to accelerate and decelerate as well.

does this apply to linear owners as well?

Re: RPM sticking at 2-3k

I think itís much less likely on non turbo cars due to less under hood heat... using the cruise regularly helps to keep the cable ends from binding.

Re: RPM sticking at 2-3k

I have a linear with a similar problem. But it doesn't have a throttle or cruise control cable. Could the cruise still be causing some issues?

Actually, you don't even have to pretend.

Here's a photo more zoomed out:

It's just below the intercooler in that photo and up and to the left from the red nub above the alternator. I can't remember which one is cruise and which is throttle, but get a buddy to watch the two cables while you press the accelerator (not in gear of course!) and the cable that doesn't move is cruise.

Also, if you have an 06 Aero, those are DBW (IIRC) so you won't be able to find any cables no matter how hard you look  spider

Re: RPM sticking at 2-3k

DBW cars won't be affected by this issue.

The cruise control cable is the one on the left, going to the box on the passenger side firewall with the orange sticker on it.

The throttle cable is the one attached to the alternator belt guard.
