Hey all, well after Mitsubishi told me that my check engine light was on (95 GSX) and I replaced the O2 sensor, there it is again. The guy at Mitsubishi said "see you should have fixed it here" (it was $240 as opposed to my $80, who would?) So I am thinking that maybe it is the wiring from the harness that you plug the O2 sensor into (on the passenger side of the head.) I still (like with the "broken" O2 sensor) get about .068 volts when I use my voltmeter on wire #76 from the ecu. My Autometer air/fuel gauge still obviously doesn't work... Any help would be much appreciated. Thanx!
