Okay, the misfire is cured, found No2 injector seals were suspect. Replaced both seals on all four injectors.Cleaned the areas where the seals are meant to do their job. There were deposits to be removed. Probably a buildup over the years.

The low cold idle problem.

This is on the B23E with the k-Jetronic CIS system.
Essentially, when starting cold, the idle is approx. 650 -700 rpm. When up to operating temp. the idle sits just under 1000rpm.

Living in a colder area ( compared to the rest of Australia ), it's essential for a good cold start.

The engine starts easily enough when cold, a couple of turns of the crank and it's away, but the low idle speed is accrentuated when selecting drive or reverse, dropping to approx. 500rpm. This can't be right !

Any suggestions on where to start would be appreciated. Thanks.
cheers
