updating this thread with fuel mileage results. jeep got consistent 22+ mpg before the injector swap.
1st tank after the swap - ~18.1 mpg
2nd tank after the swap - ~21.7 mpg
I've been doing a lot more driving than usual lately. I even ran the a/c quite a bit on the second tank, which had previously proven to decimate my fuel mileage. not so much now...not sure if the injectors are responsible, but it's a positive effect nonetheless. hoping to see my 22+ next time.
just wanted to share.
