Ok Loren I have one more question..., please forgive me but english it is not my nature language and I am a little confuse with the o2 Sensors location..

Please let me know where is located the O2 sensor BEHIND the catalytic converter; This one is the one located between the catalytic and the end of the exhaust system (tail) part # 993 606 118 01....? or the one located between the catalytic and the engine part # 993 606 128 01...? thanks a lot

It would be the one closest to the muffler.

The terminology is that the sensor before the cat is closest to engine and measures the bad gases - and the sensor after the cat should be seeing cleaned up gases.
