P0101 Mass Air Flow Circuit Range/Performance

[Donal]

I do not have empirial data, but I would check and clean the throttle body valve and passage. A relearn for the throttle body may be helpful. The Psia seems lower than what I expect. But many engine conditions influence performance. I most always do the add a temp ground thing.

Man I have the po101 every time I go above 3000 rpms. I'm thinking the cats are bad, smell rotten eggs on occasion. Did anybody have a solution for this?

The code is telling you that you have a MAF performance problem. Why are you going to the cats? Check for sealing problems at the MAF. Check connections at the MAF. Use MAF cleaner and clean it and see what happens.
