check the timing belt (least likely)check spark plugs (could be misfiring)get the catalytic converter checked, as it could be clogged and preventing your car from exhausting properly
you can get full diagnostics run on it at any dealership, then taken elsewhere for the actual work, as the Kia dealership I've had my car serviced at charged me $115 to spray brake fluid cleaner on my rear brakes.

Why is oil light on in 2000 sephia
Chevrolet Malibu surging?
I have the same problem, and there are a few sensors that do the same thing on vehicles now days. a bad tps sensor will cause: transmission shift issues, bucking, jerking, idle surging, engine cutoff, hesitation on take off, surge while cruising down highway. all of these symptoms do not have to be presant. a problem code does not light up if problem is not severe, even if codes do not come up you can still have a bad sensor. I have a 2000 Malibu 3.1, the tps is on side of throttle body at throttle plate, it is black and round, I believe the elec, connection has 3 wires!! take out 2 screws holding the tps in, pull off of throttle plate arm, when putting back on make sure you use a new o ring. when putting it on make sure that the throttle plate is closed. HOPE THIS HELPS, CARL
