This is just a wild **** thought but maybe it could be your Crank Position Sensor (CPS).....

 

^^^all that controls is the charging system an tach

 

is it possible that this -potetially damaged DV- could be the culprite for my horrible fuel milage? ive never seen over 13mpg with this truck.

 

I would probably blame most of the bad mpg on your right foot

 

I know on my 24v (granted this is a 12v with a CPS not a CSS) the CSS was causing it to stumble really hard. So figured I would throw it out there.

 

what is the CPS and the CSS for that matter?

 

Not saying at all that is the problem. But a CPS is a crank position sensor and a CSS is a camshaft sensor.

 

10-4 and wether its relevent or not? my truck has gotten 13mpg from bone stock to what it is today. like original tires bone stock. im the 2nd owner at 59,000miles. kinda why worn out parts is a hard pill for me to swallow... but never the less 13 mpg BLOWS!

 

You don't have to worry about the cps or anything alike causing your miss, those inputs are only taken into consideration on electronically controlled engines. It may not hurt to look into slipped timing. Too many things could cause poor economy and even your miss off idle but you gotta start with the smallest/easiest and start ruling things out. I'd look into air in the system first then see what it's cost to have the timing checked and then DV's
