Lambda fuel trim

[griffer500]

Hi, I having a problem with my Griffith 500, it’s running with too much fuel.
With Rover Gauge connected I have no error in relation to the lambda sensors but my Lambda fuel trim is not okay. Any idea what is wrong here?



Kind regards, Jan-Erik

Thanks Mark,

I allready use your cable and Rover gauge software.
I will use your information on http://www.g33.co.uk/pages/technical-fuel-injectio... as a guideline!.

The car is still running with a high fuel consumption. The sensor for fuel temperature and coolant temperature are the same. Is it possible that the connectors are mixed up?

Picture of the connector on the fuel rail.

The connector on the coolant sensor is brown.
According Rover gauge the car is running on a right temperature, maybe it uses another sensor?
