IH POWER
ALL MOTOR!
Lol yeah that might be my problem. Because when I pull my 4x4 lever back it takes forever to engage. You have to drive a little ways for it to kick in. And even then sometimes it will flash or kick right back out
That will probly decrease your mileage if anything. You are now sucking in hot air from around he engine bay, rather than cool air outside the fender well.Just changed my cap and rotor and took off all the stock air ductwork from the fender. Hopefully that'll boost my mileage some.
