I'm not familiar or experienced with your vehicle, but I
suspect that it is
warning you that
something is wrong with the
engine cooling system, and the
engine is overheating.
This is not good.
As soon as possible have someone who knows what he/she is doing to check out your vehicle's engine cooling system!!!!!
The fact that the engine is missing indicates the the
engine temperature is WAY too high, and to continue to run the engine will result in RUINING THE ENGINE!!!!!
When i checked it out in day light, it was actually two separate problems. 1. One spark plug lead had come loose on the distribitor causing the missing. 2. The Heat problem was a faulty sensor on the Catalytic converter on the exhaust.
Unplug the sensor and the light will go off if it is.
