Shakes or Wobbles problem
2000 Saturn SL1 135000 miles

I need advice on two issues with my car:

1) In Idle (not moving) or in Park, the engine sputters. It does not lose power, it just sputters. Sometimes, when stopped at lights, the car lurches forward a little bit. What could be causing this?

2) This might be related to #1. After driving more for about an hour on the hi-way, when I place the car in Park, the RPM's jump up and stay around 2000-4000. They don't drop until I turn the car off and turn it back on. What could be causing this?

Please help
Thank you
AJ

Any codes set? I would begin my cleaning out the throttle body and idle air control valve. You can buy throttle body cleaner at any autoparts store. Use an old toothbrush to clean plate bore, and vlave. Also look for any vacuum leaks. Cracked or unplugged hoses etc..
