Hi, I just got a 98 f 150 and every now and then out of the blue my accelerator goes to the floor and i have to b quick to turn off the truck. Then when I start it back up it's fine, then out of the blue it does it again.....wtf???

 

Sounds like a throttle cable or throttle body butterfly spring issue.

I had a late 80's Ranger that would do that with the cruise control. (The first time was right before I passed a county sheriff on the side of the road!) "Honest officer, the truck did it by ITSELF!"

Did you have cruise on?

 

Well, now you know why they sold it.

 

no

thanks chickenwire... my truck falls under a few of these reports, what do i do from here? thanks

 

I didn't read everything, but was the cause of the problem ever found?

 

I didn't study the entire article / listing I posted, but it appears there was a recall related to the speed control (cruise).

Bob - I'd take your vehicle and vin number to a Ford dealer to get a full maintenance history to see if the recall work was ever performed on your truck.
