89 turbo may start and run perfect . Next day may sound like missing 2 or three cylinders.
Next it may run fine. I'm thinking it's not the cam sensor, or it would stop, not knowing where the timing was at. I think I would suspect one on the ignition coils, before the igniter.

I'm not sure the igniter could cut out just a couple cylinders or not. Anyone know if the igniter could to that or not?
