Dodge-Charger-2007-V6-3.5 L-standard i.E. Not Hemi or SRT
Following is the problem


I was at 120-130 kmph ( ambient 105F) - engine RPM 2000 - 2500
I had been driving for about 20 minutes before this happened
The traffic situation was such that I needed sudden acceleration
I pressed the accelerator pedal hard almost to the limit
Engine RPM suddenly shot to 4,000 in an uncontrolled manner i.E. Not gradually but suddenly
Releasing the pedal did not bring down the RPM
I kept the break pedal pressed and managed to get the linear speed in control
Pulled into the hard shoulder on my left
when the car slowed down considerably, I shifted the gear lever initially to Neutral and eventually to Park
All along the engine continued to run at 4,000 RPM i.E. Even though the accelerater pedal was released, the RPM did not come down
Later I switched the engine off
The accelerater pedal was not stuck in the floor carpet etc.
I restarted the engine after a while a couple of times but the idle speed used to get raised to 4,000
I am seriously concerned with the above
I do not know if such a thing can happen even while driving normally
I suppose it is a problem related to the Electronic Throttle Control
I would like to receive any technical feed back and similar experience if any
Also any recommended checks & remedial measures
How the problem can be mitigated
How to ensure that this problem is eliminated

Your problem is probably in the electronic throttle control. But if that is the case, you should get a check engine light, as the computer will definitely see this.

If you aren't getting a code, then your problem may lie in the linkage and/or the wiring going to the throttle actuator.

You can only find the cause through a process of elimination.
