I installed a holley systemax, 50 lb injectors and a new abaco dbx 97mm mass air meter that was calibrated for the injectors before being sent out from Anderson Ford. I have a check engine light coming on saying code 66 missing mass air signal, and also a code 2000 on the PMS which says missing mass air signal. I called and talked to Danny up at Anderson and he verified the DBX was programmed, and the PMS is reading Load voltage so he thinks its just way out of tune now and the 50 lbers are just dumping fuel. The car idles, a little rough at times, revs up fine, but if you try and hold the rpms at say 2k, it just cuts out and wants to die. Car cannot be driven under normal conditions because it wants to stall as soon as it reaches 2k rpm. So basically im gonna take it up to AFM for a retune but kinda want it running right before i go up there, anything you guys got as far as ideas for things to check. Also if i unplug the mass air meter while its running, its does nothing, no change in running condition at all. Danny says it unlikey but not impossible that its a bad meter!!!
