I bought my 2000 Disco SD7 about a month and a half ago and while on the interstate on the way back to my house my service engine light came on, now the truck ran fine didnt seem to have any problems with it and as a sunday project i decided to go get the codes read today thinking that it would be something simple. My truck has about 112K on it but the interior and exterior are in mint condition as is the engine compartment and only seems to run rough every once and again when i dont have the scratch to put premium fuel in it. Anywho my ytuck threw the following codes and i need help interpreting them so that i can get an idea on what i need to fix first in order to save some money so that i can actually drive it away from the mechanic, here goes.
P0150
02 sensor cir. malfunction

P0174 System too lean (bank 2)

P0159 02 senor CTK Slow response (bank 2 sensor 2)

P1174 Manufacurer Control fuel air metering

P0300 Random/Multiple cyl. misfire

P0308 cyl. 8 misfire (this code appears twice.)

P0304 cyl. 4 misfire (this code also appears twice)

P1300 Manufacurer Contrl. Ignition sys. or misfire

P0302 Cyl. 2 Misfire

some immediate help on this would be greatly appreciated!

 

You need some serious tune up work, Give me a call and we can go over the codes and what you need to do to correct the faults.
