96 powerstroke running rough.Help please!
hey guys i need some help. i got a 96 f250 manual trannie with 276000 miles. it has been running a little rough, and has lost power.when it starts it smokes pretty good for a few minutes. when warm at idle its got a rough idle. and on the highway it just doesnt feel smooth anymore. without a load on it it still pulls hills pretty good but put just a small load on it and it lays down.i know i need to put a turbo on and that is on order but i dont think it has to do with the rough idle and smoke. everything is stock as in there is no performance upgrades,stock turbo stock size injectors. so if i could get some advice on where to start i would be thankful.
