Looks like I may have a bigger problem.
Recent problems: stalling when preparing to shift into reverse, pcodes for cylinder misfire and o2 sensor, and very poor gas mileage.
3 days ago: while driving, my brake pedal gave way... I had no breaks. Headed for a tree, I popped it in reverse bc emergency brake wouldn't work. Stepped on gas, that pedal gave way and I started flying backwards.
The rundown: power steering, starter, electrical, all fine. No more codes. But as long as its in gear, the truck will just start moving, quickly too. Ebrake did start working. All fluid levels are good, but I never checked the t-fluid and there is redish/Orange fluid leaking down the front/driver tire. When the brake pedal us pushed down, with engine on, hissing sound, more leaking, and smoke. I was very lucky to have missed a tree, a car, and then someone's property. Does this sound familiarly to anyone?

 

I will move this to the 2nd Generation Dakota Sub-Forum.

 

Check the flexible brake lines, at the driver front first. Orangy sounds like it might be brake fluid. The lines can/do fail after a while. There are two more, one on the left and one on the differential pumpkin too. If you change one you should probably change all of them.

If not that, It could be a leaking caliper.

As for the codes change the 02 sensor (not Bosch) then give it a good tuneup. A bad 02 can kill your mileage.

 

Ty, I'll let my dad know. He's helping me with it. Would a problem like that cause the accelerator to fail? My dad did check the brake line. He said it was cut. Now, I have some stupid people in my life, but I'm sure if someone would do it intentionally. That happens in the movies.

 

Brakes and the accelerator are two separate systems. One shouldn't effect the other.

Did the cable come off the throttle body?
