So are you using the overhead console? Because a chip totally messes with it. After putting on the chip the camo truck read 28-99mpg.

Try filling it up reset trip odometer drive about a quarter tank or so fill up and divide the miles by the number of gallons it took to drive that far.

Hey guys sorry my comp was down,

I just changed fuel filter(the old one had a crack in the top but couldn't see till i took it off)

Also changed oil and did tranny filter(lots of metal on the magnet) Tranny fluid smelt pretty burnt and i could only get 6qts outa it so im gunna pull drain plug and do again to get more of the garbage out. drove it around a bit today and dosnt seem any better.

I did notice something leaking from front pass side of motor, its got the whole side of frame covered past driver door. also fluid down between the heads(guessing oil havnt stuck towel down there yet.)


Im checking fuel mpg by putting in 10gal and resetting trip and runn down to same spot.


Still lost guys im going to check coolant right now.

Alright guys i just checked my anitfreeze i siphoned a lil out its a brownish color with green tint, kinda merky, taste like crap yuk, and smells like old antifreeze. not oily or anything. def need to be changed tho.

take the cold air intake off and see what happens. dont know why but every cai i installed my mpg's would drop about 5 mpg.

[FL_SmokinPSD]

Okay i really didnt notice a huge hp gain from the intake, just cool noise and knowing its getting clean air.

[FL_SmokinPSD]

okay well that didnt help at all, Someone told me maybe its my crank position sensor.....any thoughts on that?

[bockhold]

if ya havent done it yet, do it

[FL_SmokinPSD]

wheres it at? and would it be throwing a code if it were screwed up?

Also yesterday when i went to start it it was kinda like surging at idle, i turned it off and back on and it still did it, i did that a few times and it stopped surging.......ideas.

all truck has is dp tuner and muffler delete

all new oils and filters

the cps is on the right side of the harmonic balancer on the block.
