Last night I started my jeep 97 TJ and after just a few seconds it died. I tried stressing it again and turned over then almost started but didn't... tried a few more times and it turns over but nothing... while having my transmission out the plug that goes into the O2 sensor on the back side of the cat converter one of the prongs broker off... I knew that want good but plugged it in and ran it anyways. Lol. Ran fine for numerous days and prob a few hundred miles... yesterday I drove all day with not a problem until last night. Any ideas in what this could be?
