Misfire

I have recently purchased a 1987 900T16 217,000km privately and now have a
couple of problems to sort out on it.

1. Misfire: seems to occur hot and cold, between 1500-3000rpm only when
holding speed, ie. not noticed during acceleration. My initial thoughts were
an ignition or fuel problem. I've just replaced the plugs (NGK) with little
effect and have had a brief look at the distributer cap etc. Has anyone got
any advice on where things wear out first to narrow the problem down before I
start replacing leads, coils etc.

2. Catalytic converter: To my suprise (being a non-USA Australian model) it is
fitted with a catalyst. How well do these age, if it has been damaged in a
past life and it's resistance has gone up could it be causing the above
problems. Are there any negative implications (apart from environmental) on
the engine or turbo set-up by removing it.

Thanks in advance for your help, regards
James
