I've tried to get comments from other fix it sites on what I need to do. I changed the plugs, changed the air filter, used carb cleaner/fuel injector cleaner ( strong mixture) and truck still runs rough, black smoke out exhaust, tail pipe black, and fuel consumption is terrible. I had it put on diagnostic machine, no codes came up. It's not unusual to use $40 worth of fuel for just a short run.
Has anyone had this problem and if so, what did you do to fix it?
