So I've got an 07 F150 Fx4 with the flexfuel 5.4 liter and if I don't let it warm up for a few minutes it's sluggish for the fisrt 3 to 5 miles then goes away when warmed up. It doesnt matter which fuel I use either. I mostly run the e85 when I can find it but the last few tanks I've used regular. I bought it new its has 2600 miles on it. Just wandering if its normal or I should have it looked at?

 

i think i know what you are talking about, and i do experience that in the mornings when i go WOTand it lags a bit...but yeah, once its warmed up, good to go...

 

Exactly, if I go WOT, it does it then goes away. (usually when I leave late for work)

Also I notice the exhaust smells different when I'm "burnin corn". Other than that I love it. I had an '06 Stx supercrew (it had 25k when some lady ran a red light) I'm glad no one was hurt but I sure don't miss the suicide doors of the supercab. Supercrew is the way to go!!!

 

its funny though, idk if u have exhaust or not, but when i go WOT and hit lik 4K rpm, and then let off, it just kinda stutters and backfires and pops reaalllyy loud...have you ever had problems starting your car in the morning with the flexfuel when its cold? (ie: takes longer to crank?)

 

what kind of mileage do you get when you burn livestock feed?

 

I haven't had any trouble starting when cold so far. As far as mileage, It has a 30 gallon tank, costs aroung $67 to fill up get around 450-460 miles roughly. When I get a new tank I'll reset the trip and try and get a more accurate reading.

 

when burnin oil, ill get bout 265-270 miles to my tank (27 gallon tank that ive never put more than 21 gallons in??? still dont get it but) and when i burn the oil (that smells like rubbing alcohol when exiting the back side) i may get about 200-210 m/tank..but i fill up with under 50 bux, so that alleviates dishing out more money...

 

The worst part of owning an E85 drinker is where to fill up. There's only a few stations that are within a 1/2 hour drive of where I live. I'm suprised that there is MORE of a push for these vehicles. Support the local corn farmer rather than Abba Haha in some middle eastern country.
