Happiest of Monday morning to you all. Lets jump into it...
2016 Limited EL 2wd. Averaging 13-16 half city/hwy. We had been getting 18+ for a couple of years, 19+ on long hauls on hwy.
I put a Frontier Grille Guard on our Expy shortly after purchasing (MPG number above are reflective of having the bumper on). Wife recently extended her daily commute to work and I have been wildly disappointed in the milage she's been getting. I am curious if anyone has put together any before after numbers of adding grille guard and full replacement bumpers and their diminishment of MPG. I am certain it causes a decrease by disrupting the areo and slip stream stuffs. But I can't imagine the weight of a grille guard (not heavy full replacement) would make a huge difference.
I replaced the spark plugs back in August or so, gapped to recommended spec, using FORD OEM, The ones I removed her in real rough shape. I thought it would make a huge difference, but no.
While doing plug job, i pulled the throttle body and cleaned it up as well. It wasn't too dirty seeing as it had been replaced a year before on the TB issues. Pulled MAP/MAF and cleaned all three. The MAP on top of Manifold wasn't soaping wet/oily but was clearly stained brown.
Changed air filter as well at the time.
I am currently at a loss for the diminishing MPG. I expect low teens running around town, but Highway I should be getting 18 or better.
What do you all think? Wallnut the valves? Clean intake? Any other issues I'm not thinking about? Not getting any codes. No misfires. Smooth idle. No check engine light. Only issue weve had since ownership was limp mode activated by the Throttle body issues, but that was quickly resolved.
TIA
