Gtp with mass airflow trouble code
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.

Well, it turned out to be the MAF sensor. Instead of buying the $140 remaned A1-Cardone one at Advance Auto Parts, I went to a reputable junk yard here and got the entire throttle body with all sensors including a working MAF sensor. Running great now.
