The ASR light comes on as soon as i touch the throttle pedal. Previous to this I replaced all spark plugs & cables and removed the valve covers. I tried adjusting the slack, both directions, only difference is how far the pedal can be pressed before lights come on. The light also came on a couple of weeks ago, and stayed on (until I shut her down) when accelerating, full throttle.
Any suggestions what I should look for?

Here are some ASR nuggets from the MBCDs. Hopefully, they can shed light on your troubles..

Thanks, will have a look!
Here is whats happening, with the engine started the ASR lights up (and stays on) as soon as the accelerator control lever at the ”electronic accelerator reference potentiometer” (R25) starts to move. Not sure where to go from here, could it be a faulty potentiometer?
