30-45 minutes the problem becomes almost non existent. Occasionally (after 30- 45 minutes) there's a very brief reluctance off idle.
After 30- 45 minutes if I give it a large accelerator command it goes as good as ever.
There's no check engine light and I've plugged my (cheap) OBD II reader into the car and there's no codes.
The no code diagnostics in the factory manual list 8 or 9 possible components that will produce the symptoms
I've described, but I cant find anything in the manual that gives information on checking the health of those
8 or 9 components/systems.
Has anybody got an idea of the most probable cause??? or even know of a decent Subaru Tech/Mech? I'm well West of the Melbourne CBD. So a Tech West or North of the Westgate bridge would be good, as the traffic on the Westgate is hideous these days... its bad enough getting across on my bike let alone driving across

Cheers,
Alan.
