sooty plugs

(1/2) > >>

oakeedokee:
Took my spark plugs out today - and they were all black and sooty. Does this mean my mixture's wrong?

Range Rover Blues:
V8s are a sod for sooty plugs if you let them idle a lot, often the plugs need changing prematurely.  A sooty plug can denote a rich mixture, too much choke or a cold engine.  A wetish black plug is excessive oil consumption.

oakeedokee:
Well they're not wet, so that's good. It has been idling a lot just lately. Perhaps I should clean them up, give it a good run and then re-check before I go tinkering with the mixture.

muddyweb:
That would be the best bet IMHO.

Are you on carbs or EFi ?

oakeedokee:
Its a 3.5Efi
