All spark plugs are in good working order. All seated, no holes in insulation. And yes my tire pressure is ok (:o It was on the list!)

Air filter is new. I checked over vaccum hoses as well as manifold leaks, everything is good. PCV Valve is new, I took it out and is still good. Complete air system (Intake) Was dismantled and cleaned; that is all clear.

Cap and rotor are brand new. Maybe 200 miles on them, did not help the problem any. Id like to check the fuel pump relay..In the fuse box?

MAF Sensor was swapped with another, same issue.

Some problems started while I pulled my ECU to Herculine my interior. The Trooper hasnt been the same sense. I do run an MSD 6A box w/ Tach adapter. I also have switched out Ignition modules, and bypassed the MSD.
