i have a 70 notchback with issues:

i installed a megasquirt ecu and it was running fine till yesterday...
suddenly, the ignition key was locked in the lock

i couldnt get it out, and i also couldnt turn on the ignition
after some time, i got it out, but the lock isnt smooth anymore..
you have to juggle the key to turn on IG
sometimes now, when i turn on the IG, the megasquirt doent get power,
i turn off again, and it has power again...
the car also just died when driving...
could it be that the ignition switch is broken?
or is it the lock cylinder itself?
are the cylinders type 3 only, or does a bug cylinder fit?
cheers, Peter
