Technical Is it possible?

[Stark]

Is it possible that a thermostat stuck open could have been causing some/all of the perceived problems with my injectors? Perhaps because it's running too rich?

 

[custard]

it can run rich as the engine never reaches full temp so the car is always in cold start settings

:yeahthat:

but if the injection system fault light is illuminated on the dash it means the thermostat isnt related to the problem at all and there is an actual fault somewhere.
