I have a Japanese spec SPI which is running rich on idle but is fine at higher revs, this shows up clearly on a colourtune, I have checked all the various posts on the site but not found anything about this problem, The car starts and drives fine, it just smells rich when idling. Fuel consumption is average. I have checked all the vac pipes etc.
Any ideas ?
