Same with my 04 Ram

If I remember correctly , a lightning bolt light lit up on the dash

12. Electronic Throttle Control (ETC) Light 5.7L
Engines Only
This light informs you of a problem with the
Electronic Throttle Control system. If a problem
is detected the light will come on while the
engine is running. If the light remains lit with
the engine running your vehicle will usually be drivable,
however, see your dealer for service as soon as possible.
If the light is flashing when the engine is running,
immediate service is required and you may experience
reduced performance, an elevated/rough idle or engine
stall and your vehicle may require towing. The light will
come on when the ignition is first turned on and remain
on briefly as a bulb check. If the light does not come on
during starting, have the system checked by an authorized dealer.
