Magna a late starter

...
I HAVE a 1992 TR Magna with the 2.6-litre EFI engine. After 170,000km it uses a little oil, but my main complaint is that it has no power for 5-10 minutes of running after starting in the morning. It's much better when started late in the day after standing a while.

I WOULD first check the temperature sender, which tells the computer to keep the fuel injectors open a little longer during the cold running phase. The sender could be faulty, though you would normally experience some stalling and poor running if that is the case. The other possibility is that the catalytic converter is partly blocked, which can affect performance, and it's more noticeable when the engine is cold.
