Hi, I have a 94 peterbilt with a 350 cat engine. I beleive it to be a 3176, my problem is it seems to hickup for a lack of a better word once in a while.  I bought it not long ago and have not pulled anything other than an empty gravel trailer. took it out for a run oneday 12 miles did not do it, the next day it did it again. It seems that it happens at slower speeds or when starting off from a stop.Seems to be intermittenly. Could it be fuel or maybe ignition ? Thank you. Dve
