88 N/A with blocked off egr valve, RacingBeat downpipe/presilencer, larger secondary injectors everything else for the most part is stock.
Last week one of my stock primary injectors crapped out and i bought a new set of primaries. When I installed them my ilde went up a little bit to 1500 from 900 so i tried the idle adjust screws on the throttle body front and i got nothing. so i pulled the throttle body off and messed with my fast idle cam and now its idleing at 2500 im not sure if i miss aligned the fast idle cam or what. If any of you guys can help i would appreciate it alot.
thanks,
Jerm

 

just an update i pulled the throttle body off AGAIN and tweaked out the fast idle cam and tightened the throttle adjust bolt(the one by the oil metering link on the front) and now its holding at 1500RPM anyideas how to get it down?????

 

If you reused the old hard bottom injector insulators, you may have a vac leak there.

New insulators, or at least a small O-ring on the pintle cap below the insulator will close the gap.

 

You probably have a vacuum leak...Like ShureShot said, if you just replaced the injectors and didn't also replace the O-rings and grommets, that's one place to look. You also need to make sure the gaskets under the UIM and LIM are new. You might also want to give them a touch of RTV and make sure they're correctly lined up and not folded or crimped.

 

i used new o rings and gromets and when i pulled off the manifold the gasket cracked so i bought a new one of those as well. im thinking my tps is out of wack or my cam still isnt lined up properly ill find out tonight and let you know.

 

Your S4 will idle without the TPS, so you can unplug it to see if it's confusing the ECU.

Maybe back off the throttle plate hard stop some.

It's right in the center it this picture.
