V6 Gas pedal hesitation
 

Does anybody else have the issue below? I have a 2011 V6 Premium Vert.

When I am rolling slow or starting out once in a while (getting more frequent) there seems to be a hesitation from when I push the gas pedal and when the engine responds. It is quite annoying and sometimes when the engine kicks in it gives the car a jolt.

I didn't expect this from the Mustang, is this normal with the V6? I never had this issue or anything like it with my Grand Prix (which I owned for 7 years).

If this is not normal (I really hope it is not or I will be a short term Mustang owner), what would cause this? I just bought the car from a dealer in January and have the extended warranty but there should not be any issues so soon after buying the car.

Sounds like a drive by wire issue. I'd take it in. If its getting worse something isn't right.

I have add this issue before in my V6. To cure the problem I changed out the fuel filter when the oil and filter were changed out. I also used a bottle of Chevron Techron in the gas tank and use only Chevron or Esso gas. Do not used Shell as it as to much sulfur in the mix and can bring on hesitation. Do not use independent gas stations as you never know where they get there products from. Fuel filters should be changed twice a year once in the spring and once in the fall.

Twice per year fuel filter changes is excessive. Under scheduled maintenance it's usually a 50,000km interval. The 2011 up Mustangs don't actually have a serviceable fuel filter, it is built into the fuel pump/sending unit.

X2, could be as simple as a PCM reprogram.

I just know what works for the 2005 - 2009 Mustangs. Basically from November 01 to March 30 the 05 is parked in the garage. Techron in the gas tank prior to the winter park eliminates water buildup in the fuel system. The fuel filter change is simply and extra preventative maintenance step. I guess if I drove the Mustang continually, a once a year change would be o.k. ** Note to self - check out the poster's vehicle year.

He might not have the ride, but he's got the smarts. Working at a dealership doesn't hurt either.

You can't go wrong with extra maintenance if you don't mind the cost, that's for sure. That being said a fuel filter is very unlikely to clog when the vehicle is sitting. I always use stabil when I park my vehicle for the winter.

Again, a different animal than the 3.7, but the throttle response on my '07 V6 was horrible right from the start. The throttle lag drove me nuts. A tune cleared it right up...If I didn't know better, I'd think there was a physical link between the gas pedal and the throttle body. I'm not a fan of drive-by-wire.

The concerning part about yours is that it seems to be getting worse. If it was like that from day one, I would recommend picking up a tuner and some tunes...it made a world of difference with my car.

Thanks All. Could be my frustration or head that it is getting worse, I have focused on it the last few days and it does seem to be consistent around 2 seconds like one of the other posters stated (definitely not .5 seconds)

I will look at the tuners and see what can be done. Is that something the dealership does also? (I would assume so)

^^^^^^^^^^^^^^^^^
What he says. I bought a tuner on his advice and I'm glad I did. No more pedal lag. :tup

You might try fulling fuse 47 and see if that helps.I keep reading
about the computer relearn feature and how it seems to be
change back after guys put a tune on their car.

Even after putting 3.55s in my V6 and a tune it will not
spin much in first gear.Good luck and hope you find
out what it is.

WOW! I did the Fuse 47 trick and took the Vert out for a spin, is like a completely different car!! Thanks Puroman.

Unbelievable the difference in the car just from a simple fuse pull.

Thanks all for your responses.

Good to here it worked out! Props to Puroman!

Tell us more on this pulling of the fuse 47?
Is there some where we can read up on it?

Do a Google search for Fuse 47 Mustang. That is where I found out about it.

From what I understand, under the hood, in front of the battery open the fuse box, pull out #47 (When car is off) and leave it out for 10-15 minutes.

What this does is resets the throttle settings apparently. I was skeptical but read a few people trying it and saying it works so I decided to give it a try. Worked exactly as they stated it would. Throttle is sensitive now and I can feel the power in the car that was not there before (was starting to wonder about 305hp).

Saved me 400US on a tuner (at least for now) because it did work exactly as advertised.

Glad it worked.I am not sure if it lasts for long though.
The talk is that Ford might have put something in
the computer that makes it reset after some time.

I have a Bama SF3 tuner and I get performance
but only for a short time and this is with a tune.

I also hear that if you have a auto trans,that
the computer will adjust to your type of driving.

Great info, I'll check into it a little more, Thanks

.......

it can be fixed and eliminated with a proper tune from the likes of sct. I had the same issue with my 08. it is so fast now it moves before you are done thinking about it lol. I race the car a lot though so I want it fast acting. can't tell the diff from a cable . I had my car tuned at marken performance in Kitchener.highly recommended .

Hey rampant racing, been forever since we've seen you, good to have you checking in. How's things been going ?

hey appocolyps. had a terrible year this year. my 25 year old daughter passed away and we are now raising my grandson who is 17 months old on new years day. been a tough year. car has been off the road a couple years. going back on the road this spring. should run well into the 11's i would think with all the new mods to the motor.

Oh man, cars don't mean shite when you get a kick in the chops like that, I'm real sorry to hear your daughter passed on, condolences on your loss. Props for taking on raising your grandson, that's a tough go for him and for you, but having the support of the family will carry him through. I've got a buddy that was raised by grandparents, and the important thing was a loving home, which he had, turned out to be a great guy. Cars not going anywhere, but when it does, you've got your pit crew chief at your side.

^^^^^^^^^^^^
X2 On what he said. I couldn't have said it any better.

Wow I really don't know what to say, I'm very sorry for your loss.

Really sorry to hear of your loss. I get really numb when I hear these things. Hopefully the new year will bring a fresh start for you and your family.

As for the Mustang if has been off the road for a couple years you should check over the brake lines and calipers. If there has been no fluid moving through the lines the caliper tends to seize. Just food for thought.

thanks guys it is appreciated very much. yes the brakes will be looked over before we go anywhere in it. can't wait to get it out again and have some fun. I need to get back on track with life. been a very hard go of it.
