Re: black box (ruderacer)

Are you talking about the one infront of the pass. side rear wheel? If so that is the fuel pump and small resevoir. The transfer pump (in tank pump) pumps fuel into this smaller resevoir and a main pump (the one next to the black resevoir) pumps it to the injectors.

As for that noise, in the back on the pass side, right? ....it's just the fuel pump. Nothing to be concerned about.
A rough idle can be sourced out to be so many different things, so I'm not even going to try to help ya on that one, but it usually isn't the injectors.

bad idle is usually associated with a intake leak, check the boots , and all the joints and clamps, i did it , i had a leak and sure enough my idle got better, another problem could lie in the O2 system, and ISV , that you can clean , dont ask me how

i hear everyone talking about, "clean your ISV , blah blah blah i can even find the damn thing
