I pulled up to a little store had a pepsi attack, i left truck running as was walking in i heard truck idle change truck got quieter. When i got to the truck and listened it is diffenely quiter. Anyway all the sudden the mileage is better and the power is still there. I pulled the sensors and checked connections, everything looks good.
I am not complaining its just strange. I have allways used power service silver bottle since truck was new. I just cant explain it. Went to get some trees and tomatos, peppers, etc yesterday round trip 120 miles mileage was 23mpg. The sensors i pulled to check were very clean, no black soot on them. .
Very strange dont you think.
