little red plug
 

ok i seem to have lost that little red plug that comes with rb header install. the one that goes on the hose that is left after the air pump and acv removal. not the hose that comes from the intake the other hose. would this create a vaccum leak if not their because im having idle troubles.

I'll go pull it off my car quick to see.


Edit- My cars idle got screwed up after I pulled it.

so what do i use for a replacement

Go to the autoparts store and get a hose cap or if you are really ghetto use some tape over it.

Squirt some RTV silicone in there to plug it, then let it cure at least 15 minutes. I've got several vac lines plugged this way on mine, never had a prob...

i popped up my hood today to do the normal fluid check. and i was like their is something missing. so like discount auto parts or napa would have it. cause my idle is real erratic now.

i used rtv for the acv shit works great if i cant find a cap ill try that

Just use the black (good to 400*F) or red (500*F) stuff- the clear, gray, or white might not take the heat (depending, of course, on where you're putting it)...
