I have a very very rough idle when IN gear. The vibration dissipates by about 75% when I throw it into Neutral or Park. The vibration disappears entirely once the slightest bit of gas has been applied (that is, when in gear).
It's a pretty bad idle. Produces a vibration sound that sometimes hurts your ears. Once and a while, I can hear a sort of clanky noise from what sounds like the back of the car which is in rhythm with the vibration at idle. Also gone when gas is applied.
RPM speed are completely stable and calm regardless of being in N, D, or R. It runs just below 1,000. I have replaced plugs and wireset with no results. /: Any advice is appreciated
