could you tech guys take a look and tell me what you think
honda vigor 1990 , one cylinder does not work. it happened a few days ago and i felt that the car became trembling a little bit , I pulled THIS spark plug connection out and engine just nothing changed, but when i pulled any one of others, idle became much lower, i checked the spark, 4 of them were perfect and just this one was in white colour. What happens to this? Is it a engine problem? please help, thanks!
just the one spark plug is white in color? It could be a clogged injector which could be causing that cylinder to be running too lean.
