Question about 2004 Dodge Ram
When driving, the electronic throttle control light comes on and the engine bogs down, but when I let off the throttle it goes away. It does this quite often and also the cruise control does not work. I was wondering if they are related and does one have to work so the other does? Also my check engine light is on and I have checked everything under the hood and the truck runs fine other than the problem stated. Does this mean I have bad sensors in the exhast line?
You need to have the codes read. The electronic throttle relies on an APP sensor and a TPS sensor. A problem with either one of these will cause this. Also, the cruise would be affected by this, as there is no cruise servo, it's controlled be the electronic throttle body.

"EML" is an acronym for "Elektronische
Motorleistungsregelung". Loosely translated from the original German for the BMW
owner means Electrionic Engine Power
"EML" is BMW's system name for electronic throttle management. The "EML" system, in it's most basic sense consists of an accelerator pedal (with an electronic position sensor), a computer module (usu. integrated with the main engine computer), and an EDK (Elektronische Drosselklappe or Electronic throttle valve). The EDK is also known as a "drive by wire" throttle. "EDK" throttles use a computer controlled stepper motor rather than a purely mechanical linkage (usu. metal cable attached directly to the accelerator pedal) to control the opening and closing of the throttle plate.
"Drive by wire" throttles are very common
on modern vehicles starting in the late nineties up through the present day.
"Drive by wire" technology enables very precise throttle control to improve
drivability and vehicle emissions, as well as many convenience features like
electronic cruise control, traction control & stability control.
BMW first implemented "drive by wire" in very limited quantities on the most expensive & sophistocated BMW models starting in 1988.
The latest generation of advanced vehicle
features to take advandage of "drive by wire" technology are radar guided cruise
control, accident avoidance control, autonomous-driving, and autonomous-parking
