Hello,
Having a bit of a "punch up" with my 1984 280Sl. Seems to be missing, lumpy and down on power and up on fuel consumption!

I have changed:
Spark plugs
Spark plug leads including the one to the coil
Distributor cap
Rotor arm

I was beginning to wonder if it was the fuel injection, but that was all checked and found to be ok (K-jetronic)
Only thinks left are the ignition module and the coil which I guess ain't cheap.

Could somebody let me know was the ignition timing should be please!

Plus to cap it all the indicators and the hazard warning stopped working two days ago and it's MOT is next week!
Thanks in advance for any help
Malc
