Okay, I got the MAF cleaner spray from WalMart. They do look a little crusty. I will take a picture tomorrow of the MAF plug when I install the ICV plug and the DISA valve. I will then clear the codes and see what kicks out. I am still expecting the O2 sensor code to pop out. But i am hoping the other three go away.
If the MAF has an electrical fault, including wiring, you should have a MAF circuit code.
