The point to that comment was that most people forget to plug the MAF back after a filter change. You had all of the codes and symptoms that produces.

I think I would remove the throttle body and give it a good cleaning. Remove and test the IAT (Intake Air Temp) sensor just above the throttle body and make sure it is plugged in and no broken wires or bent pins. Check the hose from the valve cover to the throttle body, make sure it is attached properly and no tears. I assume you cleaned the maf properly and not spray engine de greaser or something in there?

IAT sensor test
Check the resistance of your IAT and then apply heat to the IAT sensor tip to see if the resistance decreases. If there is no change or an infinite resistance reading, this means your IAT is faulty and should be replaced.

On thread #9, You had told us 70 to 65 psi, now you are saying 165-170. This is why you got the response that you did. Please explain everything in as much detail as possible and proof-read before you post.
