1996 Dodge Ram mis-firing on all cylinders. Starts but runs poorly.I have replaced the pick- up coil and the oxygen sensor.The truck ran fine then check engine light came on and truck is coughing and bucking around 50 MPH.Truck has about 180000 miles on a 5.9 liter V8.

I would try checking the fuel pressure first .. you can rent/borrow a
pressure test at most autoparts store. post your results here .. check it with key on engine off and key on enginerunning.
