Throttle plate sticks


Asked by Sep 12, 2016 at 10:14 PM about the 2001 Daewoo Nubira 4 Dr SE Sedan

Question type: Maintenance & Repair

My 2001 Daewoo Nubira had a high idle problem, when put in park or
neutral it would idle very high 2-3K RPM. I noticed that if I closed the throttle
with my hand instead of letting it snap shut it would close a little more, which
would lower the idle back to normal. I looked at with a flashlight and it looked
pretty dirty, so I took it off and thoroughly cleaned the whole thing, and in
that time I also replaced the IACV because it was making a grinding noise.
When I put it back together I forgot which side was up on the throttle plate
and I noticed that if it was put in one way it caught just a little when closed
and when put the other way it moved freely. I put the plate on the way that
moved freely and put it back on the car. It idled great and worked the first
time I drove it. Then I drove it for a second time, about 5 miles on dusty
roads, and when I got back and put it in park it revved up to 3K RPM again. I
opened the hood and sure enough, the plate was catching. What would
cause this to happen? The oil is never low, but I did see a small pool of oil in
the intake when I pulled the tb. The spring works fine, and the cable is not
too loose or tight. Ideas?
