Throttle delay/ hesitation ‘23 limited

[JimB81]

Some things to try:

1) Turn off Auto Start Stop
2) Calibrate the Throttle Body
3) Try a new Throttle Body ~ $200

How you do calibrate the throttle body?

I did some searching, but haven't found anything concrete to support my claim. So I may be incorrect.

It’s nice to have discussions with adults… who don’t feel the need to hurl insults, ridicule, etc.
Wrong or right, both won.
Kudos sir.

IKR!

It is my understanding that the throttle body is calibrated by putting the ignition in RUN without starting the motor. After everything finishes booting, slowly depress the accelerator, hold at max for a second and then slowly release. If the intake snorkel is off, you can watch the throttle body valve respond.

I would also try turning off the Forward Collision Warning on vehicles experiencing severe hesitation on acceleration.

1) Turn off Auto Start Stop
2) Go to Uconnect->Safety/Driver->Forward Collision (Off)
3) Calibrate the Throttle Body
4) Try a new Throttle Body ~ $200

I have tried the recalibration with the gas pedal before, this is the first I am hearing about the forward collision warning system. I will give that a try in the morning. Thanks!

Try tow mode too. It’s like sport mode

Unfortunately, shutting off the forward collision warning didn't help at all. Tow mode does feel like sport mode but the delay on reacceleration from slow speed is still there. So frustrating.

 

[JimB81]

Anyone ever try a PCM tuner, like a diablo sport, to try to rectify the problem. I have a service appointment at the dealer on the 8th, I don't know why but I am not super hopeful they are going to tell me anything.

I’d try a throttle controller next and see what that does.

Most are pricey, but supposedly the 9 drive ones work. I’ve never tried them tho

I've tried everything over the past couple of months as well with no change. I hauled 1000 lbs 250 miles yesterday and it was worse because the truck was weighed down. Driving in traffic is infuriating. I'm not sure this is tenable for me long term and I just want my 4th gen back. Good luck with your dealer, mine doesn't give a crap.

Well I just dropped mine off at the dealer tonight. I will let you know if they come back with anything.

Same issues on my 19' w/ e-trq. Stop sign, full stop (start-stop off), begin to press the accelerator., nothing nothing nothing, BAM takes off. (throttle pedal re-learn didn't help). In OBD JSACN and looked at both "Acceleration Factor" and "Acceleration Threshold" and they both are set to "Filter Off". (On mine, it does indeed start rolling forward when I take my foot off the brake and before I apply to the accelerator, so it seems not as bad as the 22+ MYs)

I really hate it in the winter months. Press slowly from a stop on snow... nothing... nothing... nothing (same throttle input, no change), then BAM goes to take off and the tires spin and TC takes over.

So after my trip to the dealer they said that this is just how the truck drives. I pushed back a little bit and they went and "refreshed the transmission adaptive" honesty the first day or two I thought it made a difference. After that it was back to the same thing, I guess it quickly relearned how to drive crappy, HA !

Not sure where to go from here, I am sure if I try to sell it I will be upside down on the loan. Maybe some more research on a PCM tuner, I do think this is a software issue and not a mechanical issue. Thoughts?

I have but I am hesitant, from what i understand the pedal commander just adds gain to the output of the pedal. In my situation though, if I push hard on the pedal from the start it doesn't help, in fact it kind of makes it worse. What i am thinking is that I need the truck to be in the right gear as I am slowing down, not trying to figure out what gear I should be in after I press on the accelerator. Just a theory at this point though.

they say PC screws up your truck because it doesnt use an external power source.

I have zero experience, so just from reading the interwebs and marketing pieces…

PC doesn’t use full power, doesn’t have reverse override, if it fails…you’re limp mode.
Pedal Monster from Banks uses 12V from OBDC and has reverse lockout (doesn’t operate) and if it’s disabled it’s passthrough.
I don’t feel the need yet… but should I go that route, PM will be the way.

Again, zero experience with either… just from what I’ve gathered via reading.

Hey all,
I’m having this issue with about 12k miles on the truck. 5.7 hemi 2023 1500 limited.
from dead stop two things:
1 the truck will surge when let off the brake, I assume due to the auto/start stop?
2 really delayed throttle response From dead stop. The dealer already reflashed/ relearned the throttle body but it’s continuing. To the point i feel it can be unsafe when trying to pull out into traffic. I’m going to end up getting smacked.
Anyone else have this issue and is there a fix? If the fix is to turn options off the get the truck to work right, thats going to be a problem. Thanks for any advice…getting kinda bummed as this is my first Ram.

I have noticed the same issue with my 22. However, I also learned that when I come to a stop light and stop completely I take my foot off the brake pedal and put it back on and the next time I need to take off there is no hesitation.

I have the same acceleration issue with my 23...the dam truck just won't go! Half way down pressed and its Like riding on a puff of air for a second day or two. Absolutely hate it...will likely be the thing that makes me eventually give up the truck that I custom ordered. And I agree it's completely nerve wracking and unsafe at intersections or even slow crawling through a neighborhood or parking lot.
