Thermostat importance

[Jmac]

Yep an easy missed item. Non VAG but still Euro, i looked a t a SAAB 95 with an engine light on and drinking fuel. After the obligitory temp sensor gets fitted the light comes on again a day later. Remove thermostat and this is it 3 days later.

Ecu is simply doing what its told, engine is running cool so the injector pulse width is wider. New stat and coolant and all good. Just thought i would share.
Cheers
