I got alot of good feedback on my miss in my 97 Ram 5.9 I claened throttle body and no help. The scan says there is no misfire on any cylinders. have new plugs rotor and cap. While I was cleaning thr TB I took off a part that has a wire plug and two vac. hoses. It is right next to the TB on the drivers side. When I removed the vac, lines a bunch of black stuff came out I have no idea what it is but wonder if that has somthing to do with my truck running poorly. It is roughf at idle and seem to get better as speed increses.
Thanks
