Just three weeks ago we bought a 2003 Dodge Ram 1500 and now whenever it dips below 25 degrees or so a TERRIFYING thing happens.

You can just be driving along on the highway and the truck will SUDDENLY start accelerating. The fuel pedal suddenly sticks all the way to the floor and NO AMOUNT of braking will make it stop. It even keeps accelerating! It is the most terrifying thing to be coming up on a stop sign going 75 miles per hour and suddenly realize you are behind a truck "possessed."

We took it back to the small "mom and pop" car sales place and they had their own private mechanic look it over, lubricate the pedal, etc., and they said they couldn't find a thing wrong with it.

But it dipped back into the 20s today and it happened again! I had my small child in the car and the only way I could stop it was to just throw the thing in neutral and cut it off. It could have easily been a fatality situation, so needless to say, we'll be taking it (towing it) to an actual Dodge dealership tomorrow.

To even get it to start normally without the wheels spinning I had to open and shut the trunk. Isn't this whole thing just CRAZY?

My question is: what exactly does it sound like is going on? Has anyone ever heard of anything like this happening? Any advice as I go about dealing with the seller as well as the dealership tomorrow when I try to get it repaired?

Any thoughts or ideas are much appreciated as I've always been a sedan person and this whole truck thing is new to me. It's a pretty terrifying thing...

PLEASE HELP!

There is a post in here about the throttle sensor sticking on hemis. Check it out https://dodgeforum.com/m_122918/tm.htm

 

Help me out here.... Where is your trunk on a 2003 Ram 1500?

 

Trucks have trunks?

I'm lost here...

 

LMAO!!! I don't know what he's talking about.

I would suggest looking at the throttle body while the truck is on and in park. Have some one give it gas for a while to simulate a driving condition. The ONLY way you can get the "gas sticking" like that is if the throttle body opens up. No other way. So, there (throttle body or acceleration cable area) is your problem...

*note*: if the throttle body doesnt open, air doesn't enter the heads, no power is produced, truck dies.
if the throttle body opens, computer reads the air comming in and adds fuel accordingly. AKA "posessed"

 

I wonder if he's talking about the glovebox? That's the only thing I can think he'd be refering too. He might want to stay out of that "Foghollowfarm"..

 

your truck should still be under warranty so why not take it to a dealership and have them play with it!
