i had the same trouble with my 96 and i rebuilt the injection presure regulator and the problem went away.. ford wants 300 for a ipr and international wants 115 dollars.. and international also has a rebuild kit that is only 16 dollars... it consists of about 3 o-rings and a stamped steel nut.. i have the part number for that if you need it as they had a hard time finding it for me.. part # 1825806c92 . try that it might save you some bucks..

So what was the verdict???? Did you ever find out what was the cause? Just got back from a trip to california, pulled off the interstate at home and truck was running rough. Replaced fuel filter, helped some but not alot.

I still have not found the cause I have not done anymore with it since the snow flew. But it is better and very intermintent right now like once a month I notice it warm or cold motor. I am going to be changing the oil here soon, we will see if with the new oil it comes back real bad again if it does I think it might be an injector problem and will take it to the dealer under warranty.

Well I changed the oil, tore the filter apart, wiped the housing out really good with a rag, cleaned up the stem which sticks up in the filter really good, put it back together very carefully as to ensure the lower oring is in place and she fired up and hasn't sputtered since.

ipr or icp gets my vote. to check to see if it is the icp unplug it and your pcm will run in default mode. also your check engine light will come on but no biggy. i know of a resource for ipr's $85 dollars. and also the occasional one on ebay for cheap. i was having a serious stuttering problem under acceleration and unplugged mine(icp) and it runs a whole lot better. and i am starting to have to crank a little longer to get her to start so the ipr is gonna get a rebuild next oil change so i can extract oil from the hpop and refill with new. good luck
