1993 Loyale with EA82 SPFI. After replacing damn near everything else to fix a drivability issue (Plugs, Wires, Coil, TPS, IAC), I finally replaced the fuel injector and VOILA -- problem solved -- almost.

 

Now it idles fast (1500 rpm), and I can't figure out why. When I pulled the old fuel injector out of the throttle body, a small metal ring came out. It looks like a spacer of some kind, with three black (rubber) feet on it. I didn't see which way it was installed, and I'm not sure which way it goes back in. Anybody familiar with this spacer and the proper installation?

 

Thanks!

Cant help with the spacer but the idle may be a loose,broke,cracked or disconnected vacuum line.
