I have been getting a check engine light, about once every week or two for the past month or so. It always does it on my way home from school. So Im going from indianapolis to Ansonia, OH. I check it with the predator and it has always been turbo overboost and maf sensor. It is always both of them together. Now, dont everyone go blaming it on predator programming because I havent been running it. I have been running stock about half of the time and running 110 VA the rest of the time. WHen it comes on, I know I wasn't over 15-20lbs of boost. I figure the MaF sensor needs cleaned, what was the procedure to do this? If you need the exact codes I can get them. Let me know what you guys think.
