when I installed my header, first I had the top one in and the bottom plugged.. no CEL.. then figured the engine was running rich etc.. so got a 2nd O2 to put in second plug.. as soon as I did, 10 mins of driving CEL comes on.. so I unplug it and plug it shut.. no CEL..
my guess is that the second O2 sensor is reading like: signal = problem.. no signal = fine.. so i've run without 2nd O2 for about 5 months with no CEL... -------------------- ~Daniel~ No Longer Celica Owner.. moved on to a 03 WRX-EJ207
