Loss of Power

[FishermanJer]

Hello All,

I Have a 2021 Ram 2500 Diesel 6.7L. The other day I was towing my RV up Cabbage Hill in Oregon and when I went to give it more fuel, it felt like i had no power at all. I could put the pedal to the floor and the RPM wouldn't move. I ended up slowing down to around 30 MPH and then it finally caught and took me up the mountain with no problems. Then I was going up another hill and had to put the pedal to the floor. I have traveled with my RV many times over this mountain and have never even come close to putting it to the floor. About a month ago I had the trucks oil changed and fuel filters changed. Not sure what is happening. No Codes... Please help!

What brand fuel filters did you have installed?

How old is the air filter?

Mopar

Guaranteed genuine mopar?

Some of the “better” counterfeits on Amazon and eBay have caused reduced flow conditions.

 

[FishermanJer]

Yes I think so? It has Mopar on it... How do I tell the differences?

Dead pedal syndrome? Sounds like what my 2021 H.O. does at times under rapid acceleration.

Yes, mine too. Gets the heart rate up at those yellow lights where it is safer to go rather than slamming on the brakes. It is a weird feeling to put the pedal to the floor and have nothing happen for a second or two.

How do I fix it?

I don't think dead pedal can be fixed. Maybe with a Pedal Monster or something? Maybe someone tomorrow will know more. Not sure if that is really what you have though. Your description is a bit different than what I experience as dead pedal. The only time I see it is when I quickly slam the pedal down because I want to speed up fast, like a late yellow light. Never had it just towing uphill. But then I am more gradual with the pedal unlike the late yellow light.

Yeah, was weird when I went to push down the pedal more and had nothing. Then on the floor and still nothing. Kinda felt like a dead pedal to be honest.

Did the transmission downshift or was it lugging causing the loss of speed?

No response from transmission

Reminds me of my 47RE days when the governor pressure solenoid would go out. It wouldn’t kick down to a lower gear like it should when you get hard into the accelerator pedal.
