Re: Malibu idle problem
I've seen this type of problem before in the 2001 3.1L motor. Once it was a bad upper O2 sensor, the second time happened after changing the air filter...when pulling the airbox apart, it jostled some dirt around and the first time it ran, it sucked the dirt into the mass airflow sensor. Pulled the MAS and cleaned the resistors in there with some electric motor contact cleaner (alcohol based) and problem was solved...

Re: Malibu idle problem
The engine is designed to bump up the idle when the A/C comes on.

Re: Malibu idle problem
Have you checked the computer for codes, how many miles are on the engine, is this a cold and/or hot hard start... and any other info you can provide will help
