The code P0137 means that your downstream O2 sensor has low volts. A rich running engine makes the voltage go high, not low. If the upstream sensor is not reading a rich or lean condition, then you need to replace your downstream O2 sensor.

ITS HYDRAULIC, BUT YOU CAN ADJUST IT ON THE PEDAL, NECK BREAKER

Help! I realize I cannot assist but my 96 Sunfire does just as you stated in your posting on May 28, 2010. I assume by now you already determined the problem. Your response would be appreciated.

You have to pull the transmission pan off to acess them.

there not the easiest but I think if the plastic shroud under the lamp assembly were to be removed there not too bad on the passenger side but are slightly more difficult on the drivers side because of the wiindshield washer bottle is there...good luck hope I helped..Ps the hex screws are 7mm

you may have a faulty ECM

Hi..my name is Keith...and the oxygen sensor(s) sends a signal to your computer to control the richness or leanness....and bank 1 is the exhaust pipe comming out of the drivers side of the engine..so..you probably need to replace the O2 sensor(s) or you could have dirty fuel injectors..not letting enough fuel into the cyclinders..i hope this will help

email me at [email protected] and i will send you the diagram

The engine is running way to rich, that would be the only reason for gas in the oil, things that cause a rich mixture are leaking fuel injectors or to much fuel pressure, have these checked by a shop, also do u have a check engine light?
