Per,


My KV engine that has 306.500 kms also does that, but it only lasts for
10-15 seconds after each cold start.
I suspect it can be due to an injector, though I don't see why only one and
never more than one... Though I don't really care about that problem as the
car's been doing that ever since I've had it (264.000 kms) and this summer
it should be over with the 20vt conversion :-))))
If someone has some enlightment for us, please do share it!
