your running rich. What year and size engine do you have?

I see your other post, thy to not make multiple posts on the same topic. The fuel pressure regulator on the spider injectors your truck has can leak causing the truck to run rich. Get the codes read and post them back. I'm ecpecting a System Rich or something along those lines.

Yes, get the codes read. Autozone does it for free, but sometimes they give you the wrong definition just get the code number itself.
