recently it happens several times that after starting the truck the rpm gauge falls down to zero although the engine is idling.then the orange engine light comes on. if I turn off the truck and restart it again it is as it should be.
I'm wondering if there is sensor going bad or a something else.
your input greatly will be appreciated.
