02 Explorer with O2 sensor problem and a few other questions

[steve63933]

I have code for bank 1 sensor 1 O2 sensor and I am wondering which of the 4 it is?

Will a bad O2 sensor cause the rooten egg smell when you get on the gas hard or is that only if a cat. converter(s) are stopping up?

I also have a spark knock when speeding up but it sounds nothing like the timing chain problem many have.

One more issue that may involve the first two is that the intake looks to be leaking around the seems with alot of dust biuld up around the seems. Would this cause a spark knock or O2 sensor to show a fault?


One more question, the air bag connection under my passengers seat is also working when it wants and my air bag light is on I had it checked and it was the passenger seat connection under the seat I have cleaned this connector several times to only have it mess up with a week or so. My question is could I just cut the connector out and tie the wires together. It seems this would fix it.

Thanks!!!!

I would check out the intake issue you mentioned first , it can cause issues with o2 sensors and the injectors could be dumping too much fuel in the cylinders that might be why you have the rotten egg smell.

thats where i would start anyway

bank 1 is the left side (driver side)
bank 2 is the right side (passenger)
sensor 1 is the front and 2 is the rear

bank 1 sensor 1 is the left front (before the cat) sensor

hope this helps
