Ok so I have a 99 Pontiac Grand Prix 3.8 non supercharged and I installed a cold air intake on it a while go and I've been getting a p0650 for a while and I can feel my engine misfiring. So my question is because the PCM is right in the air intake system and the factory air filter set up was protecting it could the cold air have caused the problem or just the lack of protection may have helped cause a problem?

What was your code definition for that code? I can only find that code related to trucks and other engines. Maybe P0560?

Malfunction Indicator Lamp (MIL) Control Circuit Output drive moduels (ODM’*) are used by the powertrain control module (PCM) to turn on many of the current-driven devices that are needed to control various engine and transaxle functions. Each ODM is capable of controlling up to 7 separate outputs by applying ground to the device whish the PCM is commanding ON. Unlike quad diver modules (QDM’*) used in prior model years, ODM’* have the capability of diagnosing each output circuit individually. DTC P0650 set indicates an improper voltage level on the output circuit that control the MIL.
