o2 sensor problems

**LS1buckey** · 06-04-2007, 04:59 PM

Okay I have had these codes for a cuple of months now, one is a p0137 {o2 sensor bank 1 sensor 2 low volts} and the other code is the same code except bank 2 sensor 2. The car is a 1999 trans am Ls1 5.7L. I don't know what's causing this. Thier both new sensors and the plugs on them are good as far as I can tell. I also checked my grounds, Witch seem to be in good shape. What ever it is I'm pretty sure it's what's causing my car to choke from time to time...witch is not good. Plz anyone any help will be very appreiciated. thanx.

No I'm not under 80k anymore, was when I got it. Thanks for the info, I'm going to get the cats gutted this weekend and get an o2 simulator. We'll see how that goes.
