Hey there guy's just wanted to pick your brains!
Got a merc 200te on a k reg with the 2lt 8v lump, having a few missfire issues but they are intermitent.
Changed plug's lead's dizzy cap and rotor arm. Seems to run fine then just sometimes drops down to a very lumpy 500rpm especailly if sat in traffic, next thing it will clear itself.
Occasionally feels like getting no throttle response as well, this is usually after it has been missing.
Any ideas or advice will be greatly recieved.
