Hi Mr. Mike
Sorry it took me a while to get back but I had an accident and I’m just know getting around again.
I have only owned my Disco for two months and have ordered all new O-2 sensors. I bought an ODB2 code reader. I first got a lot of codes. Misfire on each cylinder, gear 1, 2, 3 & 4 ratio incorrect, system too lean bank 1 and of cores O-2 bank 2 sensor 1. I also got a 1174, 1300 code but I have not found what they are yet. I then cleared the codes and ran it until it died and only got the O-2 code. When it died I checked an there is no spark at the plug wires. I have replaced the wires and plugs last month. Oh yea I did not find a v/c leak.
Thanks for any help you can give me!!

 

So what exactly are the current codes?

 

The curent code is 150. The list of codes before I cleared them was, P174,P171,P150,P1174,P1300,P301,P301,P305,P731,P73 4,P102,P733 AND P734.
I start it up and it runs for about 15 to 20 minutes and then dies. I check the spark by puting spark checker on the wire and there is no spark. I keep trying every few min. and the checker shows a spark and it starts on the other 7 cyl. and run find for a few more min. then dies again.

 

From what I know a bad O2 sensor(s) will not cause engine to stall esp. after it run for 20 min. Bad O2 sensor will cause CE light, but usually the on-board computer will be able to compensate for a bad O2 sensor

 

I found and removed the crank sensor. I found a small pice of mettle on the sensor probe, it was a little smaller then a bee bee. I think this may havecaused my problem! Could it?
