1phtram Posted July 21, 2005 Share Posted July 21, 2005 Hey guys, my girl drives a 91 Legacy with the multi-point injected engine. When it first starts up and when coming to a stop, the idle fluctuates from 1000 almost down to zero, and it stumbles, real rough. I hooked up the black connectors and got these codes: 14 Injector #1 inoperative... (though all cylinders are firing) 16 Injector #3 inoperative... 22 Knock sensor abnormal voltage produced in knock sensor monitor cicuit sets in regular fuel map and retards ignition timing XX 24 Air control valve inoperative. Now....what do I need to replace or clean? Havent run the other diagnostic test yet, with the green connectors. Any help would be great.

Legacy777 Posted July 21, 2005 Share Posted July 21, 2005 What I'd recommend doing is resetting the ECU, drive the car around, and see what codes come back. Quote Link to comment Share on other sites More sharing options...
