Unless I've completely miss-read the manual.. where did you get this?

I didn't think the TB would even actuate unless it was turned on. Just curious, not calling you out.

This procedure re-sets(re-sync's) the TPS on the throttle body with the gas pedal.

That didn't work. I tried it twice. Tomorrow I'm going to take out my gotts mod and put back the stock intake piece. Maybe that's what is causing this?

Mine usually idles at about 600 RPMs when I reach operating temp. It might drop to a bit above 500 if I have to hit the brakes hard coming to a stop. Mine has a bit of roughness to it after I hit operating temp, but I'm chalking that up to the exhaust manifold leak skewing the fuel trim on one bank. Just gotta get the time to get that fixed.

If my exhaust pipe is black, that usually indicates a leak is somewhere right?

Yes

Any specific way on how I can find the leak?

Truck is still running rough. At 600rpm. Only at idle is it rough. Shakes the whole truck. I just cleaned the throttle body again. Still rough. I'm suspecting injectors could be at fault? What do y'all think?

I'm dealing with the samething currently....I've had the plugs changed along with a new fuel filter, cleaned the TB and MAF sensor, inspected the FPDM, ran seafoam through a few tanks of fuel, and had high-flows installed this past weekend.

It seems that alot are experiencing this same rough idle....there's quite a few threads going currently on the matter.
