My car is idling like a champ again. Got those replacement injector pintles from ebay the other day, so I pulled the rail and installed one on the injector which was missing a pintle. While I had the rail off this time, I also installed those 2g quick-release injector clips that Chris (89Mirageman) sent me recently. The motor was still idle surging....turns out, the BAC (?) or idle control screw had backed out a bunch of turns, for whatever reason, have seen this before, just hadn't thought to check since I still have that rubber plug covering it. I installed a new o-ring and then set the idle to a cool 750 rpms and went for a drive. She is all back to normal!
