It sounds to me like your ignition timing may be off. Is it also hard to start? Possibly a manifold vacuum leak. Check out your engines tune up.
Engine timing is VERY retarded. My first guess: the distributor clamp has loosened.
Major engine failure?
No, a rusted flywheel will not cause the engine not to turn over.
No, low gas cannot cause a Check Engine light to turn on. There would have to be a problem within the engine or the engine wiring for that light to come on.
No, but something that could cause uneven idle could cause the check engine light to turn on.No, but something that could cause uneven idle could cause the check engine light to turn on.
it doesn't or it shouldent'
There are pages of things that will turn the check engine light on. You need to have it checked for codes.
Dead battery, seized engine, lack of air or gas,
It would be very rare for a P1684 code to turn the light on.
It can.
Faulty light bulbs, damaged engine.
