starts up and revs high and then falls flat to a rough idle and stalls. Only code is 41.

there is no code 41 it is either a 14 or a 42 the code 42 deals with the ignition system meaning module and pickup coil i'll send the way to check it. also check for vacuum leak and fuel pump pressure 41-47 if port fuel and 9-11 if tbi.
