Ok guys i have a problem. I was driven my truck home from work friday i thought i smelled smoke. As i got closer to home a lit puff of smoke started to roll out of my vent above my radio. My truck is an 01 Cummins mostly stock 70hp injectors and have a Edge with Attitude with hot code. There is nothing that isnt working.Everything works. I pulled the dash out so i could see but nothing showing up. Can anybody give me any ideas what it could be or some help. Thanks
