So was in the process of adjusting the main rack and was almost there . . turned it lean about three clicks and now the car will start . .run for a second or two . then abruptly stall. I talked with Mark at MFI Werks and he assured me three clicks would not cause the car to not run so the problem must be somewhere else. I checked coil resistance, ok . fuel pressure . .ok . . ignition wiring . . ok . . it has the 123 ignition . . all ok. What am I missing!? I am showing the car next week to a potential buyer so . . I need to fix this!!!!!!!!!!!!! And yes I did turn the rack back to where I started and still the same symptoms.
