First the distributor with it's hall sensor issue.

Second came the dead coil.

Third - timing

Engine now starts, runs ok, but once warmed up and I disconnect thee
Temp II sensor - it runs like crap. Like running on three cylinders.
Can't get it up to speed either for the timing check.

Do I maybe have something happening between the ECU and an injector when
Temp II is disconnected?

Also - if the basic timing is set - Rotor in distributor pointing at the
case mark - and the mark on the pulley at the split in the case - is
that close enough to run it to drive a bit. Having trouble finding a
working tach and I need desperately to go shopping for one on Monday.

Thanks

John
