Alright, startin to get pissed. This is what i did!!! Car ran perfect, I removed my Cobra Intake, 42lb injectors, stock fuel regulator and my PMAS mass air meter, and I installed a Systemax Intake, 50 lb injectors, a Kirban AFPR, and an Abaco DBx mass air meter calibrated for my injectors. Car will not idle, and cant be driven as the car dies at about 5 mph. Now I first thought it was a vacuum leak like the lower intake didnt seat correctly so i re did, and still the same problem. If i unplug the DBX while the car is running there is no change at all. BUT if i plug in a stock mass air sensor it will idle perfect and not stall out. The KOEO is telling me a code 66 and the PMS is telling me 2000 which is a missing mass air signal. Is there anything that whould cause this other than a bad sensor?? I called Danny Biggs at Anderson and Im sending it back to him so he can verify if its a good or bad meter. If this thing turns out to be good, I have no idea what the problem is. Any Help or Ideas? You guys think I got a back sensor???
