I always write ignition instead of injection, I think that it has something
to do with the swedish spelling... But most of the time i catch it before I
hit send, this one slipped thru.

You might want to try a idle control valve from an old audi or vw, I think
they are pwm based, and they are closed when powerless.

Very impressive!

Exactly!

I come to think about a JK flip-flop in toggle mode, with this you could
easily make the car miss every other spark. Without thinking further about
this I sense that combinations of JK flip-flops can give you most patterns.
But I think that a 'pic' will save you a lot of headache in this case.

I think that you can afford to experiment a bit then :)
