One thing I forgot to mention in the first message is that I cleaned the mass air flow sensor changed to a new air filter reset the code error and the engine light comes back on with the same P0102 fault. Checked the PID'S and the MAF stays at 9 sec and never changes no matter what RPM you are running at. Is this normal? I would think it would change? Should I replace the MAF sensor? I also have removed the EGR valve and cleaned it and the port it bolts to. I have not done anything to the EGR pressure sensor.
