Rich running from cold

[astraagh!]

My 1.4spi is running very rich when started from cold - if I have to wait for the traffic to pass when joining the main road it hunts and smells of petrol. A classic case of "flooding" really.

I think its ok when warm, emissions were fine for recent MOT, fuel consumption is about 38mpg localy and about 45mpg on the motorway - about what I would expect for an 18 year old.

Any suggestions?

They're meant to run rich from cold.

Remember back on old cars you had a choke cable? Pulling that made them run rich too.

I agree m8 should be alot beta when weather warms up

The spi system is a piece of **** is the first problem.
There is very blatantly something wrong if it is hunting and smelling of petrol.
It's very true zirconia and titania lambdas won't work until 300C has been attained, this can take as much as 45 seconds on a cold engine, other cars use a better sensor called HEGO, heated exhaust gas oxygen sensor, same as you have but has a tiny heater circuit within it so it is up to temp quicker.
Running rich, it will not be anything remotely like a older car with a carburettor, the ecu will most likely ignore the lambda reading totally for a timed period if under a certain temp, known from the coolant temp sensor, and subsitute a fixed value under warm up.
That economy is excellent, so you know the lambda is okay, so I'd look elsewhere, I get 36-38 out of a 1.4 MPI auto on local runs, so yours sounds about right.
It may well be the SPI unit needs cleaning, ultrasonically that is, a very common problem on these, and well worth doing.

Thanks all for replies, if I thrash it trying to find any discernable performance it does about 25mpg! So best to look as if I actualy dont care and let it take its time, it always gets there!

I did put in some injection cleaner and that made a small difference.
