I think its the 157 which is mass air related I believe, it seems to only happen when I pin it for a bit and will be on when I lay off then soon after goes away.. but it doesn't always happen

Have you ran the codes? By your post it sounds like you haven't just wanna make sure. You will also get one once in a while for the egr valve

Are you clearing the KAM after you retrieve codes each time? Just making sure.

If you have a meter, you can do some voltage testing at the MAF.

Good luck.

did it come on before cleaning it? JT probably knows more about this stuff then I do. I'm just pulling stuff out my butt that could be possible issues
