As the title says, my Formie won't run with the MAF installed. I tried two other brand new MAFS and had the same results. I also tried swapping the MAF relays, but that didn't help either. In other words, the MAF is good and the relays are good so I don't know what the problem is. A buddy of mine read the wires and they checked good. He also thinks the computer is good because the scanner is getting readings from it. TPS is good too if that matters. I'm not sure what the heck to do next. Any ideas?
