I think the universal ones are wide band so compared with OEM they are much better and cope with outer limits better

 

ye i happen to be a big boy so this is something that i cant handle by myself, dammot another trip to my uncles looks like im taking more days off.
So how many post cats do i have and should i change then both or is there a way to check to see whats the bad one.

 

3.0 has 2 pre and 2 post

 

**** so i have to buy 2, hmmmmm thanks avant

 

The code you indicated shows bank 1 as the culprit, so you only "need" to replace the post cat on bank one?

Is bank one the passenger side or drivers side, I dunno? Guessing passenger side, Dave?

 

left hand drive opposed to right hand drive, in the UK its RHD and a common problem due to cold shock to the sensor ( snow and ice ),

bank one regardless of country is looking from the front of the car is on the left and most software say it as when your sitting behind the steering wheel which confuses even me lol
