	 2002 Ford F-250 Super Duty Lariat 7.3L Misfire 
		
		Hope you can give me some insight. The pickup run great at idle, but you get about 40 to 50 miles at transmission up shift sometime it will miss. When it misses it feels just like a spark plug wire miss fire. (yes I known it does not have plug wires) Go up...
