Searched the forums and the internet for causes for these codes. After several weeks of a local small shop finding and fixing my camshaft position sensor codes, I now have the new ones listed for the O2 sensor. Jeep runs great with 1 very rare issue of it just dying while at a complete stop randomly. The dying has been happening for about a year and only has happened about 6-8 times. Engine sounds normal. Only recent mods have been (a year ago) geared to 4.88, locker in the rear and ARB on-board air. Any assistance would be greatly appreciated.
