Totally failing crank sensor Mark......as opposed to one with a crap signal.

Normaly a bit intermittent as its often due to a wire break

72 is not a Motronic code.

Try disconnecting the MAF as a little test

Ok, any vac leaks?

Does it start if you apply light throttle?

If it will run as described it does sudgest a possible vac leak or a sticking idle valve.

When it ran, was it lumpy or nice and smooth?

Sorry, my mistake Code 72 relating to DIS is for the GM Multec ECU but I`m pretty sure on the Motronic 2.8.1 72 is the throttle switch not running on full load
