code P1371 & P1373

[Rudy R]

i have been having some issues with my Disco, you may or may not have seen the post.

I believe i got all the carbon out of the throttle body, but I keep getting these codes..
today along with these codes I had these two others but now are gone

i would get the two codes along with P308 # 8 cyl

so I removed the spark plug and cleaned it now its gone

the other was P1193 open circuit O2 sensor

what I did was... don't know if good Idea or not was removed plugs 1& 3 because the code P1371 & 1373 call for these cyl's ( did them one at a time) and squirted some OIL EATER degreaser in the hole were the spark plug goes. i put a shop towel over the hole and turned the key
the engine shot out the degreaser now brown.. my guess is it removed some of the other crap in the cyl.

so I put everything back and took it for a drive so far no CODES.

I will drive to work and hope for the best..
