o2 sensor or simulator
 

My SES light came on, so I went to Auto Zone and the computer showed codes for the bank 2 sensor. I'm getting FLP long tubes in a few weeks, and I might use the off-road pipes occasionally. My question is, should I replace the sensors or buy simulators?
Thanks in advance, I'll appreciate any input!
:D

If you are getting the FLPs and getting them installed soon, may as well just get the sims..

the simms are for the rear O2 sensors, aren't they?

You can run them front and rear.

You may have to run rear sims. But the fronts sensors you can leave on if you don't want to spend the extra money.

no need to change the front sensors, just run simms in the rear.

Uhhh ... that's a big negative there, Blkknight. O2 sims are strictly a replacement for the rear O2s.

No. You can only use the sims in the rear. The front ones are the ones responsible for mixture control. The rear ones are to ensure the catalysts are working correctly. The sims fool the computer into thinking the cats are good, even if they are missing.
