Q: Vibrating and shaking after putting intake manifold gaskets

asked by on

Oil leaking down into the spark plug wells can causes the plugs to short out to the cylinder head, yielding the misfire you are experiencing. Replacing your valve cover gaskets, the plugs, and cleaning out the spark plug wells, and the rubber boots from the plug wires should resolve this problem.
