swapped the MAP sensor and ignition module from my other 93 with no results. I have replaced the fuel pump in the front tank due to an inoperative fuel sending unit. I'm at lost on what to check next. I'm at the point of taking it to a Ford dealership, but I don't have good feelings as to them finding the problem but to start replacing parts that have already been replaced. and charge me an arm and leg. At this time I would almost be willing to give up one of them.
