plumster Posted March 27, 2022 Share Posted March 27, 2022 (edited) Can any of you folks explain why the spark plug just in number 1 cylinder regularly get sooty? It cause the odd miss & is disconcerting, its stopping me from going on any long runs, once cleaned car is smooth & revvy but after a few miles seems to do it again. Any suggestions welcome, cheers.
