I now have 350 miles on my Lariat and I brought it back to the dealer already for a delay when I hit the gas. Each time I try to pull out in traffic the truck will not respond. Where are the 300 horsepower? I drove another '04 today and it felt the same. The dealer cannot give me an answer, but they also feel the problem. Also, I haven't gotten more than 11 M.P.G. since purchase. Any feedback? Thanks.

 

could possibly be a slipping tranny. Also, most new cars take some break-in time, and if you push them too hard (or too soft) for the first thousand miles it can lead to a lack of proper mating in the cylinders, which leads to leakage of unburned fuel into the crank case - this can lower your gas mileage. Here's a great article on engine break-in.

While the article is about diesel engines, it may help you out too.

Do you get the same hesitation on the highway when you pass someone, or is it only hesitating from a standstill?

 

The only time I seem to notice the delay is when I try to trick it when it's sitting in the driveway in park. I was curious about the delay when someone else mentioned it, so I went out to test it. Sitting in park, I can very QUICKLY hit the gas pedal so it goes at least half way down and immediately let go. The engine only revs up to about 1,000 RPM. I thought it was kinda funny. BUT...I've never noticed a delay while driving. If I mash the gas pedal, within a split second it revs up and does it's thing.

As far as milage goes, I've been driving mine quite a bit (850 miles on it so far, had it since this past Friday) and it seems to hover around the 14 to 14.5 mpg range. Of course, this is what the computer says. I don't always trust them, so I finally set my trip computer so I can figure it out myself next time I get gas.

 

The system on the F150 uses no accelerator cables. Look under the dash and you will see an electrical harness coming out of the gas pedal assy. Look on drivers side of throttle body and you will see an electric motor, no cables. The system is drive by wire, so there is a slight delay for the throttle body to actuate on initial accell.

 

Hmmm... is this something that can be reprogrammed?

 

I'm not looking to race around, I just want to feel like I have control of the truck. My F-250 w/5.4 (265hp) felt more responsive than my new 150. It's definitely drivable, but it concerns me when I'm pulling into traffic from a standstill. Thanks for the feedback.

 

The ford was built to seem not to "slam you against your seat". It was designed like this for towing and such, not racing. Just find the shift points and before the tach gets there, let off the gas and then floor it, that will get you going. Its what i have to do w/ my four banger jeep on the freeway

 

I don't know...mine zips off a hell of a lot faster than the Cavalier I was driving before I bought the truck. Plenty of power and if there's a delay, it's so slight I don't know it's there.

 

Hey Danno,

I definitely notice the delay. Also going from super duty to F150.
I think it's just one of those things you have to get used to.
The throttle on the 250 is very responsive, and I miss that a lot.
Also, 3000 miles and have not gotten over 11 mpg, same as with super duty so don't really care but did expect better.
As much as I like the new F150, I think the next truck will be super duty.

Thanks for the reply Mick, you'd think the 150 would fly around compared to the 250. Not that I want to, but I don't think I could spin these 18' wheels except in the sand. I do love the truck (I'd better for $35,000), I just need to get used to it.

 

Despite the delay, floor it from a stop and I guarantee you will spin those wheels.
Just for kicks (and trying to use up the factory tires) I've left serious rubber on the road at take off. Just go full throttle and keep it there.
It also leaves you with a silly grin on your face.

 

Okay, maybe it's a little immature but really, what's cooler than spinning 18"'s in a full sized truck? And, yes, this truck will definitely spin 'em even with 3.73 limited slip.

And about the original post here... I don't notice a delay.

 

I had an annoying delay in my STX but it seemed to get better over time. I've got 1500 miles now and I barely notice a delay at all. Nice response when I stomp on it from a stop.

 

In a way, I spin my tires all the time on turns (from a stop) Ok, 1 tire anyway. I have the limited slip axle and it must be tight because I always hear the inside rear tire on a turn wanting to break loose a little. More so if you get on the gas. It's not hopping, just acting normal.

I don't notice a delay while driving. Only if I hit the peddle real quick when parked and it doesn't respond immediately. If I'm driving and I stomp on the peddle, it downshifts and gives me that sweet roar and off we go...
