I have a b21f w/ k-jet injection on my '82. Car has 135k. The car was idling rough and surging idle while cold, I suspected a sticky air control valve (this is the canister on top of the intake, do I have my terminology right???) I removed it and per the BB, flushed it out with carb cleaner and also probed the little piece on the inside with a screwdriver. While I was at it I removed the injectors and soaked them in injector cleaner for a couple of hours. Upon re-assembly the car idles much worse. (didnt replace injectors in their original location, but shouldnt matter right??) When I disconnect the Air control valve (harness), there is no change in idle. With the air control valve harness removed, I can get the idle to smooth out if I tap the valve. Also, the injectors are very loose in their holders, I didnt get a chance to clean all of the crud out of their seats in the head. Is my air control valve shot?? Does anybody have a test to see if the valve is getting the proper signals?? I did purchase some new bosch injectors and holders from The Parts Bin last night, any tips for proper installation (cleaning the seating surfaces in the head??)


thanks for the tips!!
