I have a 2004 Ram 2500 with a 5.7 hemi. The issue I am having is when I start it up everything runs good. As soon as I start driving it runs fine and then the ETC light starts flashing and lose throttle. I have changed out the throttle body, the TPS, I have checked all my wiring, vacuum lines and I am at a loss of where to look now. It has been plaguing me for over 2 weeks. If anyone can help it would be greatly appreciated. Thank you
