I am reviving something from the past…
So I was having problems with my shaky idle, turned out to the spark plugs. Ok so after that I kind of still feel a slight shake here and there, in an average car that will be perfectly normal but not for a Cadillac.
Ok so the other day I just unplugged the vacuum line that goes to the vacuum tank. Drove the car with the open vacuum (free to air) until today and what do you know…NO SHAKES AT ALL
. I mean shouldn’t be the other way?
Obviously now the line is plugged back and here and there I can fell a small shake.
