My car has a normal cold start, but when it is heated up, it idles super low and vibrates way too much, not just in drive, but when in neutral as well. I feel it might be the intake manifold is clogged somewhere, from what I have seen from similar Saturn problems on this site, anyone have any suggestions on how to fix a low idle problem on this Saturn L200? Thanks!

With the car in drive and idling low turn on the Ac if it works?Does the idle smooth out?If so you need a updated engine control module calibration.I have seen that before on those cars when I worked at the saturn dealer.
