I was replacing primary and secondary injector seals, grommets, insulators, and PD.
In order to do so, you have to take off the TMIC, and upper intake manifold.
easy enough.

so once i completed that task and was putting everything back together, i broke the oil injection metering distribution spider. the vacuum lines were hardened, and 2 of the 4 broke off. So I decided premixing would work.

I capped off the oil injection nozzles and the line going to them from the throttle body, pointed towards the firewall. (the largest line, in the middle of the THREE lines on a s4 TII TB)

so then no big deal, I removed the OMP linkage, and then proceeded to re-install the UIM.
I capped off all lines that were going to the spider, and then routed the primary fuel injector bleed to the top line of the 3 on the TB.

then last, (and this is where I'm not sure), I routed the bottom line to the check valve right next to it, and then I routed the line from the double throttle to the check valve. I think it's right, but I can't find pics.

I have everything back together and I start it up, and it automatically revs to 4-4500rpm and stays there.
it very well may be the throttle linkage, or cable is seized, it has cracks on it from where it is wearing. I have a replacement one, but I know it's a B to do. but is there any other reason for it to do this high idling?


also for the vacuum gurus, does my routing of the vacuum lines sound correct? I know since its a S4 there's 3 nipples, S5's have a an air bleed for the secondary injectors also, but S4s don't.

Thanks in advance!
