Sucks to change plugs, ask mitch. And the egr’s soot up and cause misfires. And the injectors sometimes plug up as well as fuel pressure regulators going bad. Oh, and the frame around the control arms arent welded very well, but not an issue if truck isnt lifted.
The fuel pump ground wire breaks too, think its on left rear frame rail ahead of the bumper.
there were a lot of those around here years ago.
