2003 Dodge Truck 2003 Dodge 4X4 5.7 HEMI ETC problem?

Engine Mechanical problem
2003 Dodge Truck V8 Four Wheel Drive Automatic

The ETC light in the dash is flashing.
The truck RPM surges and pops thru the throttle body.
Fuel pressure is 53 psi and did not find any vacuum leaks.
Only code was crank position sensor which I replaced which cleared the code and it hasn't come back.
Even with the ETC unplugged when the truck starts it surges and pops sometimes.
Replaced plugs and wires.
Is the problem with the electronic pedal or the electronic throttle control on intake?
