Got an 94 accord with stock f22 vtec motor....old motor broke down so we bought another same motor....did the swap and now the motor is shaking u start it...and when just sitting...but if u drive it, its perfect....I thought it was spark plugs and I changed them but still the same thing...no change....NEED HELP!!!!!...

 

i drive 91 prelude si while im still working on my 92 accord..and my engine bugs when its on idle.i change my spark plugs and im running my frends 8.8mm wires,i also adjusted the valve clearance,idk if that would help the problem, but it did get rid of the tapping

i open up my dizzy and i found out that my rotor and dizzy cap are getting worn out..i thnk dats whats cuzing the engine shake in idle and my rpm keeps dropping down below 600rpm.weak spark????hopefully not my external coil.
