Bought A used one over a year ago and have kept up maintaince, great truck just getting old and having troubles. Need Help bad any response would be greatly appreciated
First it started running bad and found high presure oil lines leaking changed orings and fixed it. Then got to skipping going down the road and cam sensor ran better than it ever has. Now I crank it in the morning and it smokes somethin alwful and misses until it gets to operating temp and has no power. Went off every shadtree mech in the world and replaced fuel heater no luck. If u let it sit for a day u can't hardly crank it. Some day when it is warm it runs rough and misses put ur foot in it and it runs grear. Now it has started bucking and jumping again a few time andhave to stop turn key off and go again after that it runs fine. Then u can let it idle and it starts running ruff. Very happy with truck just tired of changing parts with no luck. The smoke is very bad and the exhaust smeels very bad. Wanting to put a towing chip in it but want it runnig back to it natral form before adding n e haelp would be greatly appreiated oh yea 7.3 power stroke with turbo 150000 miles

 

bad smell sounds like unburned fuel
could be under valve cover harness or connections
try checking connection where harness plugs in at valve covers
can find lots of help at Ford Trucks Enthuests FTE on 7.3 forum
