Message	Hey all ive never ran a O2 test thru the ECU before, had always done MODE II with the engine off. Tried the O2 test just a few minutes ago and the LED/Check Engine light(s) do not flash when i start the engine, hold 2k rpms, etc. Any ideas as to why I would not be able to run the O2 test? Noticed these two wires clipped at the ECU(the white & brown at the top) ================================= 1991 NA 2+2 - Pearl White - Auto 1996 NA Coupe - Arctic White - 5Speed 1990 TT Coupe - Aztec Red - 5Speed
