Just drove 500miles with trailer in tow. Before i left oil was changed, alison filter, and fuel filter 1500miles prior to the rest. Truck had no signs of problems other than a little smokey untill warm. Started fine and idled good as well. Wasnt even halfway through trip when i noticed that it was idling very eratic ( dosent show on tach, but really rough. can feel it in cab. pop hood and motor dances from side to side) I noticed the rough idle in town at a stop light. Once back on the hwy i noticed that if the truck fell or was pushed into a 5-4 shift it would buck really hard(allmost like the key was turned off....then turned back on) Would only do this on a down shift. Woke up this morning unhooked the banks and had same problems, only now it will buck in any gear on a WOT run. Once to speed though its got lots of power to hold trailer at hwy speeds and smoothes right out as far as the shake at idle.Wanted to try changing fuel filter and realized that i didnt have one here:o: Will try that tomorrow. Ive tried a search and found similar symptoms with the Fuel press regulator. Was wondering if a set of injectors might also be the problem:confused: The crankcase isnt overfull and oil smells good so i dont think theres any fuel in it. Seems weird that this came on as fast as it did, beeing that the truck was fine prior to leaving. Bad fuel might also be a problem but you would think that the problems would have started right away.Im going to try the fuel filter tomorrow and see what that does. Any ideas on what else might be causing this? Im thinking that shes gotta have a doctors appointment...........Hopefully just day surgery:eek:
Changed fuel filter today and as suspected it was clean and problems still exist. If 6gun is unhooked it still idles rough but dosent hesitate as much as when its hooked up.........Another idea ive had is that the tranny is slipping and the banks is defueling once it sees slipage??? Still dosent explain rough idle.
Thanx Tys
