There are no codes left. Ive only owned this vehicle about 2 months. The last of the codes i was getting was P0171 and P0174. I drove the vehicle around today and got nothing. Its seems to be running smoother and better. The engine was replaced by land rover early in its life according to the last owner as im the 3rd. So its hard to tell what those cats have been thru. Im at 135000 miles, and have fixed quite a few things on it. MAF was unplugged, it was also only firing on 7 cylinders as one of the plug wires was bad. Passenger side O2 sensor was bad. Im getting it worked out a few things at a time.

Head gasket is ok for now anyways, seems to be leaking some oil in the rear from somewhere im assuming, the valve or valley gaskets, those will be next.

 

So what did you do with the one good cat?

 

Had to replace the cats on the old D1 as they had become ineffective.
One did rattle a bit.

1997 Land Rover replace catalytic converter and head gaskets

 

Still in my garage

 

Bring it to a metal scrap yard, probably at least $100 worth.
