Hesitation while accelerating

[dynasty_365]

ok guys it started last night while i was on my way to work. the car itself is shifting fine its just when i'm on the gas and going it seems like i have a little hesitation while its accelerating like it lags then pics up speed. i have a 2012 gt 6sp manual with 3.73 gears.

reading online most people who have had the problem usually have bad sensor or dirty MAF or something what do u guys think? either way when i get off tomorrow morning i'm head to the dealership and let them check it out since the car is only a month old lets put that warranty to work ya know

Hi dynasty_365,

I agree that with this being such a new vehicle, you shouldn't hesitate to bring it to the dealer. That's what they are there for. I know it is rather soon to have to make a dealer visit. Please let me know if I can be of any assistance.

went to the dealership this morning and they wanted to keep the car over the weekend but i couldnt leave my vehicle over the weekend on such short notice. so i'm going to bring it back on tuesday when i'm off from work and let them work on it since i dont go back to work til wednesday night. hopefully its nothing serious. hell u can't even tell anything is wrong. it shifts fine and accelerates fine up until im like in fourth and if i mash fully on the gas pedal it accelerates but has a pause or lag or something before it completely goes wide open throttle.

if i gradually increase the speed in fourth its not the there but when i mash on it to get on it it does it. i jst dont know. any thoughts?

i know its time for an oil change cuz i'm right at 3000 miles and my oil life says 45 percent. online it says the MAF maybe dirty or the air filter maker need to b cleaned or changed. the car isn't making any weird noises or throwing any check engine lights. it runs fine excpet when i try to get on it in about 4 gear or so. i dnt think the cluth is slipping so oh well to the dealership my baby goes

No, I'm pretty sure it's not the oil or the air filter. Unless the factory workers decided to use old filters (sarcasm).

At what rpm is the engine when you get the hesitation? You may be at to low of an engine speed to get a good accel.

 

[dynasty_365]

I'm not sure. Hasnt Been out the house since early this morning. When I go out tomorrow I'll see what rpm it does it at. I know last night when I drove it it didn't do it but when I drove it home from work it did it and it's really only in like 4th gear when I get on it wot.

Answers online vary from bad sensors to fuel pump or fuel sensor problem so idk. Hopefully it not something that they have to have my car forever for

YES. Turn off traction control, then do it. Problem should go away. The car senses impending power, and the electronic nannies kick in hard. It has happened to me in Sport mode also, but is fine when I turn off traction control or turn off traction control and advancetrack.

2011 Mustang GT Acceleration!!?? - Ford Mustang Forums

found this online. Couple people have had the problem. SoMe say it's a sensor others say it's the way the throttle is hooked up with some kind of wire connection. Jst doing research. Either way it's going to the dealership Tuesday morning when i get off work.

Also think I have that tick that some people have. Drove my car to work tonight no radio or anything on jst listening and feeling the car and heard like a ting ting ting type of noise. Faint but I heard it so when I got off the interstate finally and stopped a red light and Iheard it clear as day but online says it's not a proble and caused no issue in anybodys car and is fixed with a simple additive

 

[dynasty_365]

acceleration hesitation. Finding that many people have had this problem. Really hope it's a fix at the dealership cuz I hadn't felt this until now. But if they say it's normal torque management then I guess Ill have me a tuner real soon

My experience in GMs with the same condition is that turning off the traction control solves the problem. It's not really a bug, but just aggressive safety profile of the traction control strategy. I never thought about modifications to this through a tune, but I guess it makes sense. I would say, on a wet road, you might just like it better.

Yes, it is most likely traction control (which solved the issue for me also). But a tune does not solve this, it just amplifies the problem since it adds more horsepower, and thus traction control kicks in more often.

However, there is always the chance of a bad sensor or something, so I will stay tuned to see what the dealer comes up with.

ok sorry it took so long to update. but after the going to the dealership they didn't see anything wrong but i got my oil changed and that was at 3100 miles and i haven't had a problem out of the car since then. i'm at 6100 miles now and the last couple of days ive been having that acceleration issue again. it kinda bogs down but anyway tonight i decided to go for a little drive just to check things out and cruise a little and soon as i was bout to get on the interstate the check engine light came on and the infamous ticking that some people have is coming from the engine on the driverside under the valve cover.

so i turned arund and headed home. everytime i accelerat the ticking increases its pace and i can hear it. so i get home do some research online then head back outside to check the car again since its cool down and of course the ticking is gone but the check engine light is still on. so technically thats a goodthing since now when they scan for codes it should b throwing a code up now since the check engine light is on in the car.

i noticed that im having the accelertion problem around 45% oil life same as last time. wonder if that means anything. i mean i'm only 3000 miles off of my last oil change and last time the oil changed fixed theproblem i wonder if it will again. but hell the check engine light is on so i'm guessing its something. i'll b at the dealership first thing in the morning before they even open

 

[dynasty_365]

so while doing some research seems like a few people have had this problem with the new 5.0 with it bogging down and having a slump in the accleration. check this out and read the comments also
