Could be something with emissions if it's kickn back black smoke. what exatcly is the truck doing though man?
I'll try this out later this week after my friend gets his truck back from his mom.As mentioned the sensor for the gauge is in the head. You can easily test the gauge to make sure it's the sensor that needs to be replaced. Take the sensor wire and ground it somewhere on the truck. Turn the truck "on" not started and the gauge should peg all the way one way (up/hot).
It's not doing much anymore, it runs smooth since I replaced the sensor. When you gas it from idle to take off it blows out a fairly large cloud of soot-like black smoke. If it's being driven and you keep on the pedal the smoke fades down to a gray golor. Exhaust doesn't smell rich at all though, it's pure carbon coming out. I'm gonna seafoam it when I test the sensor as stated above, to see if the cylinders are dirty.Could be something with emissions if it's kickn back black smoke. what exatcly is the truck doing though man?
