Your car may fall under the class action suit being settled by GM due to its requirement of the use of Dexcool. It forms a brown "sludge" that causes more damage to the car. My head gasket has had to be replaced twice in less than 3 years. Search for GM and Dexcool and see what you can find about the suit. Best of luck! Another possibility is that the fan is not running while the car is on. This can be fixed easily with a hot-wire under the hood of the car that bypasses electrical systems and makes sure the fan is blowing at all times when the car is on.

The RPMs and the engine of the 2001 Oldsmobile Alero might surge if there is a problem with the oxygen or fuel sensor. It may also surge if there is a problem with the fuel injectors or the fuel filter.

The Alero is made by Oldsmobile not Chrysler. My first suspicion would be a failed fuel pump or clogged fuel filter.

If the car has high miles, try checking the catalytic converter. If it is clogged it will cause the vehicle to lose power.
