2000 Durango continues to accelerate after pedal is pressed
If i even touch the pedal the motor jumps up to 1700 or so and does not come down for a second or two. Ive checked the throttle and it is not sticking the butterfly flaps close properly. It does this even at normal temp. I can not figure it out.

I have noticed that if you keep the 'A' pedal down it simply revs beyond 3K and doesn't actually accelerate. The trick is to ease off the 'A' pedal, see the rev coming down and then accelerate again. This will save fuel also. You will see it cruising at around 45 miles just above .5K rev when you do this.
Throttle-by-wire systems like yours probably has means there is no physical linkage (cable or rod) interconnecting the accelerator pedal to the throttle body. Instead both talk to the computer via wires. The gas pedal is like a volume control on a radio and can never be felt "moving" when cruise control is engaged and making throttle adjustments such as going up or down a hill like older system did. A bad "sender" on the throttle pedal, bad or loose wiring to the computer, bad computer, bad wiring from computer to throttle body or intermittently bad electric actuator motor on/in the throttle body can all give the symptoms of "no throttle control" you describe. As for the battery being discharged, a bad trunk light switch could keep the trunk light on at all times but you cannot see this when the lid is closed. Immediately touching the trunk light bulb quickly after opening the trunk will tell you if it's staying on, it will be hot as heck. The same goes for the glove compartment light. A keyless entry system always uses power so it can listen for the signal from your keyfob to unlock the door, as does the time clock in dash or radio.
This process must be carried out in normal mode (not sports mode). On a
flat road, the transmission fluid temperature must be above 60° C (140°
f) and below 100° C (212° f) (vehicle at normal operating temperature
will ensure that the transmission fluid temperature is above 60° C (140°
9. Accelerate from rest with
light throttle (do not exceed the upper rev limit in appendix 1). 1-2,
2-3, 3-4 shifts must occur with engine speed between the following
limits:. Note: Do not move the accelerator pedal during shifts.
10. Continue to accelerate gently to 50 mph (80 km/h) so that transmission shifts into 5th gear.
11. Go into overrun and let the transmission shift down into 4th gear without braking.
12. Brake gently to a standstill and hold footbrake on for at least 15 seconds.
13. This process should be carried out at least five times.

First check for a loose hose or a vacuum leak. If you do not find a leak most likely the throttle position sensor is stuck and causing the truck to idle high. The throttle position sensor sticks, and if this happens you will need to replace it.
P2299-BRAKE PEDAL POSITION / ACCELERATOR PEDAL POSITION INCOMPATIBLE
The PCM recognizes a brake application following the APPS showing a
fixed pedal opening. Temporary or permanent. Internally the PCM will
reduce throttle opening below driver demand. One trip fault and the
code will be set within 5 seconds. ETC light will illuminate, the light
will only stay illuminated while DTC is active.
DRIVER PRESSING ACCELERATOR PEDAL, THEN PRESSING BRAKE PEDAL, AND CONTINUES TO HOLD THEM DOWN SIMULTANEOUSLY
STOP LAMP SWITCH
The most likely cause of this DTC is
Brake Torquing the engine by pressing the Accelerator pedal and the
pressing the Brake Pedal.
