I just replaced the intake and supercharger gaskets. It runs a lot better. The only thing I noticed with the Mass Airflow code was that the idle jumps up and down after it is warmed up and a little while I am driving it. Is there any way to adjust this? Is there anything else that could cause the Mass Airflow code besides the Mass Airflow sensor? I just sank a bunch of money into the gaskets and don't want to waste any money on parts that aren't bad. Thanks for any help you guys can offer.
