I have been having some issues with poor engine running recently. I used the OBD II diagnostic tool and had P0116, P0132, P1327 & P0130 and have noticed recently that there were large soot deposits below the exhaust pipe when starting the engine so decided to give it a service. When changing the spark plugs I noticed that they were really black soot, checked the lambda sensor and it was the same. I replaced the plugs and have ordered a new lambda sensor as I'm sure it can't be reading properly but am reluctant to just replace the plugs and lambda without knowing why there's so much soot on them.
Firstly, any suggestions as to why there is so much soot and secondly if i replace the lambda sensor is it likely to reduce the soot and fix the engine juddering or could it be the cat?
Cheers
