Re: check engine.
is it some sort of a serious problem??
This might have caused due to the Oxygen sensor failure.
Or blockage in the vaccum pipes.
If it was blinking then it would have been a serious issue.
The second stage would lead any unburnt fuel being dumped again to the engine and the exhaust gases again return to the engine, which may further damage the critical engine components.
On any occasion such incidents will generate error code, which will pin point the exact fault through On Board Diagnostics(OBD).
So better hurry up to the nearest A.S.S(Dealership).
