D1’s been down for 2 weeks, between myself and the mechanic shop no resolve. Tried 3 different mafs 1 new and 2 known good mafs from running D1’s. The codes point to the maf but obviously not it. New fuel pump, pressure correct, etc. Unplugged maf goes to pre set values and runs right. From what I read maf signals ECU to fuel. I’m going to try a known good ECU and see if that fixes it. Read several posts with similar problem and a lot of detailed tests and parts replaced but no real solutions. Any ideas appreciated.
