Help with Code
Hey fellas, I am at a lost. After installing the FLP's system, I get a check engine light (P0137H) This happened after three weeks of the installation. It has to do with O2 Sensors. I checked all the connections and make sure they are not loose. So far, nothing is out of the ordinary from what I can see. Anyone else experienced this after installing your headers? Any leads would greatly appreciated. If not, I might have to bring it in to the dealer and have them check the wiring make sure its not faulty with the sensor or the wiring.
Thanks fellas.

Re: Help with Code (ICULUKN-C5)
I got that code before, I think it was because of a 'slow' O2 sensor. I was told to ignore it by my tuner. You can get rid of it with LS1 edit.
Thanks for the reply.

Several things can cause this.
Since you have an H in the code it is intermittent.
Is the lead from the sensor touching a hot header and shorting out? Also could there be an exhaust leak (sensor reads this as lean and puts out low voltage)? Or is the sensor itself is not firmly in place? Also the gasket has to be good.
Finally, the sensor itself could be bad.
