Truck Hesitates when accelerating


Asked by Feb 08, 2016 at 07:47 PM about the 2006 Ford F-150 FX4 SuperCrew Styleside 4WD

Question type: Maintenance & Repair

I can be driving down the road and my truck rides fine. I'll be going 30mph
and step on the gas and it kinda hesitates, it will rev real quick then actually
accelerate. I guess it is thinking about it and then kicks in. Also even then
once I am flooring it it doesnt seem to accelerate very fast. I have Googled
some other threads to see what I could find and try myself (I am not a car
genius). I bought a new fuel pump and a new throttle positioning sensor
and will install this weekend. But I didnt know if maybe it could be
something else and/or are there any more ideas you think it could be
related to?

Thank you for the help.

Dirty fuel injectors, run some cleaner threw the gas, On the fuel pump all you would have to do is check the fuel pressure to see if it is good.

And when you say "it will rev real quick then actually accelerate" makes me think the trany is slipping.

I recently replaced both VVT solenoids in my 2004 FX4 Supercrew and what a difference it made. Parts are about $50 ea on Amazon, took about 15 minutes to do the drivers side and 5 minutes for the passenger. I could not believe the difference it made in acceleration response time. My truck has 198,500 miles and I noticed it lagging upon acceleration and just overall lacking acceleration for quite some time. For $100 I think you will be happy with the results.

If the engine is increasing in RPM's and you are not accelerating, then suspect tranny slippage.

If u already bought the TPS sensor, replace it and see if it helps, it may have a bad spot in it that doesn't accelerate smoothly but bad VVT also give u the same condition

Forgot to say but I have replaced both VVT Solenoids. It has helped when the truck starts cold it doesn't make a loud banging noise for the first few seconds anymore. The old VVT's were definitely in need of changing.


Gotcha - So let me ask you this since we are basically driving the same truck. Does it feel like "Slack" when you step on it, rather than slip. Kind of Sluggish/Gutless


Yeah I guess it could be considered more slack than slip


Ok - are you running a K and N filter? Mine made a mess of my MASS Air flow sensor - I pulled it out and sprayed it down real good and that made acceleration a lot smoother with less of a slack feeling. I am also running larger tires, 2" lift, heavy winch/bumper and a fiberglass bedcover. I succumbed to some of that being a factor plus the 198K miles. If that doesn't help, I 'm out of ideas and will sit back and learn as other post here


HA, almost the same truck. I dont have a K&N filter but a cheaper Spectre cold air intake. I read in another forum that could be a problem as well, went out and bought some cleaner for it so we shall see tomorrow if it works. Still have a long list of fixes for this weekend, because it needs it plus maintenance. fun fun


Looks Good quinwerk - mines a little dirty


and a little nicer. That pic was from when I first got it. Thanks for all the help I appreciate it.


Anytime - I hope that fixes her up for you
