My 91manual 5.0 has ported stock parts, lots of bolt ons, #24 lb injectors, and a FMS letter cam (E?). I checked that the timing is advancing with the Spout plug in. It has Ford fuel injection, but it acts like I need to pull the choke out until it is warmed up a bit. For the youngsters, that means a baaaaad idle and it is likely to die without more foot feed until warm. After it warms up some, it runs and idles fine. Does anyone have good ideas for this quirk or is it the big cam? I know of no one within a three hour, one way, drive for a chip and dyno tune. I know what to do for a Holley, but that does not apply here.
