idle adjustment
I have adjusted the idle adjust screw on top of the TB and it does absolutely nothing... at all... I am trying to adjust for the RRM PB V2 and no matter which way I turn it nothing happens to the idle, stays around 500-700 and dips all the time due to the pb misfire. now, if I reset the ECU after fiddling with the screw, it will die, within a few seconds so I turned it back to stock and I get a rough idle. I turn it up from there and the intake makes a louder sucking sound but the idle stays where it is at. now maybe I am just restarted (very possible) but I don't know what I should do, any clues?

Maybe it's the other screw? I know there are two screws on the TB. And for some reason, I think it's the bottom one you adjust. *but I could be totally wrong*
Maybe give RRM a call?

i've never heard of turning that screw. you could always loosen the braket on the front of the intake manifold and slide it to the left a bit. but on the piggyback rough idling, i dont think raising the idle helped. It didnt work for me, it just made the idle higher so that the backfire was rougher.

well, if I turn the screw (counter clock wise I think) it comes up towards me and the intake starts making a loud hissing sound, but RPM's do not budge at all. check all vaccuum lines and they are all good and the seals are great on everything else, if I take off the piggy everything seems to run fine, just want to raise the idle a bit so the dips aren't so bad when it gets into that mood.

Agreed, Same Problem. Tho when i increased the idle with the screw it went UP, but then just goes back to normal after awhile. Still randomly dies & idles like ****.

so uh, 3 people now, wtf, it has to be something with the piggy, I am lost, anyone know enough about these crackhead motors to know how to fix them so we don't have this issue, we get rid of the bumpy idle and bam, no CEL and bam, clean power, there has to be a reason why the 04's aren't having the issue as much or a way to make it alot less noticeable and not take a performance hit.

i've used that screw numerous times to adjust my idle. it has worked everytime in conjunction with RRM PB V.1 you need to wait till the car warms up and adjust the idle slowly. pay close attention, you'll notice the difference. although the bump doesn't go away with V.1, it seems to linger around a lot less.

thats the problem, i've adjusted after driving the car, while its running at its low idle, arounnd 600RPMs or so and moved the f'ing screw 6 full tunrs in either direction and it does nothing to idle nothing at all, the only difference it made was, like I said, when I turned it counter clockwise it started making a hissing noise like it was sucking in more air the idle does not move at all in any way shape and or form. Im about to make a movie showing what happens because it is crazy.

again, use the bracket on the front of the intake manifold, just not too much. and adjusting the idle wont fix your rough idle. it will just rough idle at higher rpms making them more noticeable. contact rrm and send the piggyback back to get the smooth idle map.
