You are correct in that there is no idle adjustment screw for that engine. Every thing is done electronically through the computer and related sensors.

What you are probably experiencing is due to a bad throttle position sensor. When this sensor fails, it can allow the computer to think the throttle is depressed which in turn makes the engine rev up very high. This is a quite common thing on those engines so I'd start there for sure.

I think a lot of improvement for this car has to be done by manufacturers..The Chevy Malibu has back seat troubles, claims GM. A redesign is reportedly in the works. Article source:Chevy Malibu a cramped pain in the rear
