my engine keeps going on and off. it says it po132 02sensor high voltage... i heard its not the 02 sensor. i checked the fuse and its good. the wires aare good. i have heard it might be the exhaust manifold that triggers that code to come on...any help if that true or not..my jeep keeeps hesitating at times. it looks like this

 

Hello. I can't really say if that's the cause of your troubles as my XJ has a similar crack and isnt experiencing any of those problems. Pretty much all XJ exhaust manifolds seem to crack in that spot it seems. My nieces boyfriends Grand Cherokee had a bigger crack at that point and he asked me to get him a new/used one from the junkyard. I must have looked at 10 of them before I found one that wasn't cracked in that spot.

 

well my engine light comes on every once and a while. and the code is po132. i looked around and some ppl said it might be that. it hesitates a little when the light comes on. but not always. just thought id ask. and see what i advice i can get
