I would use a 96 oz jug of diesel clean to start...

The oil won't bother filters, but the diesel kleen might loosen a bunch of crud.

Oh, APPS is "accelerator pedal position sensor"...

 

dam thats alot of power service. how much oil should i use and what kind i cant seem to find it on here

 

Its a lot, but only one tankful...

2-cycle oil is what you are looking for...I don't remember the dosage. There are lots of threads on it...

 

ok ill it out hope it works. thank you very much

 

Just the walmart gallon jug is fine for two stroke oil! One ounce per gallon!

 

i just checked my apps. it has 6 wires goin to it and i found the voltage goin in and the signal wire coming out wat are the other 3 i know one is a ground. the voltage goin in is 4.9 volts and comin out at full throttle is 4.5 volts and at idle its .445 volts does this sound right

 

i put a qt to a tank every once in a while in my 6.7

 

i just checked my apps and i found the power wire, ground, and signal wire. what are the other 3 for? i got 4.9 volts for power and at idle the signal wire is at .445 volts and 4.5 volts at full throttle. does this sound right?
