I recently purchased a '92 F-150. This truck has a rebuilt 5.0 in it with 15K, my question is when I accerlate at a normal pace it runs fine. When I accerlate like I'm trying to haul the mail it stutters quite a bit I am thinking this is due to dirty fuel injectors, but I do not want to dump that kind of money in if there is a chance that it could be another problem i.e. fuel filter, spark plugs or many of the other items. So my question is has anyone else had this problem and what did you do to fix it?



Thanks R
