video 2004 3.5 Chrysler Pacifica Rpm going up by itself while at red light
 

o I have a video of when my car was at a red light it started to making loud sounds and the rpm was going up by itself it did it in park as well also the gear selector made a pop sound like it went into place but it still made the sound
when I got home it smelt like something burnt.

More to this madness

Four days before this happen
I don't know if this was a problem but I was on E and while going to grab gas the car started to make a weird and loud sound and when trying to accelerate the rpm was not moving and stood at 2k then the car started to sound the same and I safely went to the gas station.
Video:
Note the Idle Pully is squeaking gonna replace soon also the timing belt was just changed with pump

what are the codes for the check engine light?

P04701 Exhaust Gas Recircular
P0403G Exhaust Gas Recircular
P0032G H02S Heater Control

the egr will make the rpm go high if stuck open.
