I had an idle problem on my car where the idle would sometimes go really high in park. I ended up replacing the throttle body, which fixed the problem for a few days, then this happened. I was driving home from school, about a twenty minute drive on a highway, and when I tried to stop at a stop sign the car kept pulling, the rpm's would not drop below 2000. I rolled the rest of the signs and made it home, since I had had a problem with a high idle before I anticipated it would rev when I shifted it and sure enough when I put it in park it shot up to around 5000 before I could shut it off. I went to throttle and it was stuck partially open, but the cable was loose. I forced it to close the rest of the way, but I did not have time to mess with it. The next day I went back and the throttle was sticking, so I turned the idle screw about half a turn and the plate did not bind. I test drove it and did not have any problems. Then today I drove it to school without any problems, but on the way back it stuck at 2000 at the same stop sign. I rolled home and sure enough the throttle was sticking again, and when I manually closed it the car idled fine. What would cause this to happen? I cleaned the throttle when I put it on, so it is not carbon build-up, and I just did a smoke vacuum test, which did not turn up anything. Is it possible the TPS is sticking? Any ideas as to why the throttle only sticks in certain situations?
have the same problem?
