Does unhooking the bat for a while mess up your trip set?

So i noticed that my MPG are lower than normal. This past week i filled up a full tank of gas. drove around until 3/4 a tank. did some mods over the weekend (added interior leds, bed lights, reverse lights, and DIF breather MOD).

here is my question. Should any of this effect my MPG? I don't think it should?


I'm down to 1/4 of a tank and have only clocked about 160 miles!!!

I usually average 18 MPG. WTF? I think our tanks are around 18/19 gal tanks right? So i should be getting over 300 miles per tank. At this rate i'l barely brake 200!

I did unhook the bat while doing the light mods? could this reset my trip set or something with the computer to effect MPG?


Could i have done the DIFF breather mod wrong, maybe the diff is not BREATHING?

any ideas?

and no have been using the same gas, and driving the same way

 

unhooking the battery will reset your A and B trips, but will not affect your ODO. Before unhooking your battery, write down your trip numbers and odometer reading and use that for the future.

 

I beleive our tanks are 20 or 21 gal, I can't remmeber which.

 

ok i feel better now
Time to re calculate MPG's with a fresh tank
