Hi, mutungi.

See here for the Trionic flash codes. Seven flashes is air/fuel mixture. If it is using a lot of fuel, then either the mixture is too rich due to a fault, and the teh code reflect this, or is has been too lean due to a fault and Trionic has made it very rich to compansate.

Initially, I'd lean towards the former. A rich mixture on a Trionic engine could be due, as far as I know, to:

1) Fuel pressure regulator
2) Intake air temperature sensor
3) Coolant temperature sensor

4) An injector partially stuck open due to fault/clogging by dirt- check your plugs for tell tale signs

Oh, yeah.

All the others will make all plugs turn sooty. A faulty injector will affect only one plug.
