I have a 2000 Disco with 160k miles. In the past year I have replaced the F. Drive Shaft, MAF and Fuel Pump.

I currently have a oil leakyet to be determined, a coolant leakmost likely a head gasket, and an oxygen sensor problem.

I replaced my Bank 2 Senor 1 02 and a week later it failed. I replaced that one and the new one failed again.

There are no other codes now. Before I replaced the sensor for the second time-I had arunning lean code.

What do I need to check to repair the sensor problem. If i replace all 4 will this actually help or do I need to do something else?

Any help is appreciated,
Clint

 

PM me your tele number so I can get you back on track. In the mean time quit throwing parts at the truck.
