It was the MAF all along. It took 4 separate scans to pick up the code. I ordered a cheap MAF from Oreilly's because I need to get to job tomorrow, that's if $140 is considered cheap. There were cheaper ones for less than $100 but I didn't recognize any of the brands. I'm loving this Foxwell scanner. It can do all sorts of things.
