I have excess black smoke, and looks like soot on tail pipe. The truck starts up fine, then stalls out. You can however start the truck and keep your foot on the gas, and it will keep running, but black smoke pours from the tailpipe, and runs super rough, and when going get alot of hesiation and surging. I am lost where to start to troubleshoot and find the problem. Any help would be great. Thanks.
