Just picked up another fox on sat but it has a stumbling problem. If you give it more than 1/4 pedal of gas it just stumbles and falls flat on its face like it is out of fuel. the car has 70mm throttle body, some kind of aftermarket pump (had 38psi at idle), new fuel filter, exhaust, and some other suspension stuff. now on to the fun part. after looking at the injectors i saw two different part numbered injectors. a couple were a 9f593 (could not find a flow rating on them) and some were e67e-b4b (which are supposedly 14 lbers). i think i have narrowed it down to this but just want to make sure before i pop on a set of reman fords from ebay. any help is appreciated.
