My first EFI rebuild just curious on thoughts about a no idle I have. First its a 1990 Mustang 5.0. t5, 8.8 upgraded from 3.08 to 4.10, engine- .40 over, .01 shaved deck, .510 roller cam, ported gt40 heads, new valves and dual springs 190I, 160E, ported intake, port matched upper to lower intake and exhaust to 1 5/8 header, 70mm t body and intake(intake tube modified to fit, 24lb injectors, MSD ignition w/9.0 wires, motorcraft platinum plugs, 1.6 roller rockers set to resistance on push rod then 1/2 turn and locked down. 3/4" intake spacer portmatched to clear tall rocker covers. runs and sounds good(besides a rocker arm tick) over 2000 rpm. release pedal or linkage and she stalls. idle air is new, TP is new and set at .92-.93v but the MAF is stock for a 55mm intake and 19lb injectors. Lets hear some thoughts on what is causing the no idle out of my 2 choices or something else I haven't thought of.
