I did it, I finally have th worst mileage KJ. Marty and I accomplished this task very easily yesterday...
I got 3.5 MPG in town. How?? Easy, carbuerated V-8 power

!!!!
No not really, one of my evap system hoses is leaking, and I guess it is causing the decline in power and MPG, only code I have is P044 (minor evap system leak) Part costs $40, half tank of gas to go about 25 miles $25, I think I will buy the part...
But really, could you imagine an AMC 360 TH400 Dana 44's front and rear on a KJ...

If I roll it it may come....
