anyone had this problem? truck seems a little down on power, but when going down the road, under 2000 rpm motor shudders quite a bit, mostly in overdrive, as soon as it reaches 2000 rpm it smooths out. dosen't smoke that I can see. have the same problem running propane.
could it be injectors???

hello!!!:)

try some stanadyne and change your fuel filter.

first thing I tried was a new filter, where can a person get standine? truck only has 12000 mi. on my 3rd filter.
