The air fuel mixture sensor is probably starting to fail. You need to have a simple diagnosis done at the shop and then have it replaced - they are usually not much a reputable mechanical shops. When the motor warms up your air/fuel mixture changes hence the rough idle etc. Hope this helps.

look for loosen battery wires, corrosion in them. check ground wire all the way to the engine block make sure its connected right and check ground to the body of your vehicle.

Testimonial: "wires corroded really bad. just replacet it and it fixed it. thanks"

SOURCE: myservice engine light came today rogh in idle at light rpms seem a little high this is a 98 saturn sl2 I think engine is a 1.9

the check engine light means that a code has been set. the code will reference a faulty system that must be diagnosed and repaired. sorry for the vagueness, but there are e gads of codes that can cause the rough idling

most aftermarket parts places will scan the car for free. this will give you an idea of where to start.

Could be the fast idle sensor check to see that the vacume line is hooked up properly.
