read fault codes but it could be the engine immobiliser or the crank position sensor

this code means you have a bad electrical connection. check the wires that plug into the coil and follow looking for a short or corrosion in the connector. it is shorting out and not sending power to coil. your coils may still be fine just the wiring going to it. check your grounds too

There may be a misunderstanding here.Yes the warning light comes on when the oil pressure drops below 5psi.If the light comes on and the switch is working correctly, the oil pressure is not good. Any problem with the pump or the screen would make the pressure not good.If the oil pressure has been checked with a mechanical gauge and it is above 20psi, the switch or the wiring could be faulty.You would need to have the pressure checked to know.

Either the damper door is not redirecting air flow OR your air duct clogged with debris. If you get great air volume thru all the other vents I would believe the problem is with your damper not functioning properly.
