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?
