new to the forums, have a bit problem with my 01 dakota. when i cut my headlights on the speedo stops working and all the "dummy" lights come on like the parking break light and everything. "no cel" and the truck sounds like its going to die. the rpms fall quickly and idles at abuot 4xx rpms. any idea what could cause this? im thinking its the ecm and thats also what everyone is telling me. so if you have any ideas let me know, TIA
