My girlfriend has a 96 Sport 4.0 OHV Auto, the past couple weeks it has been throwing some codes:
O2 sensor circuit slow response (bank 1, sensor 1)
O2 sensor circuit slow response (bank 2, sensor 1)
System too lean (bank 1)
System too lean (bank 2)
They don't all apear together, it's hit and miss which ones will pop up, sometimes they go away completely.
It started running rough and stalled on her once when stopping at stop sign.
Fixed an ehaust leak about a month ago, between the last cat and muffler (downstream of sensors); the leak had been appearent for about 3 weeks before fixed.
I am thinking that the O2 sensors are the cause and need to be replaced. I was about to just got pick them up but then thoughed i'd ask for other opinions first. So, does anyone have an idea of what they think it may be? Do you think I would be right in replacing the O2's? I was thinking it could be the cats also, but my first guess is O2's
Any thoughts are welcome, and thank you in advance!
