conley3.1 Posted October 22, 2003 Report Share Posted October 22, 2003 I found two round plugs with green rubber o-rings around them while installing an engine, they are near the back of the engine, and one of them is an oxygen sensor, but i don't konw what the other is. Is it another o2 sensor? Thanks Quote Link to comment Share on other sites More sharing options...
