Check engine light is always on while car is running. Idles really rough with vibration through the steering wheel. I can see the steering wheel shake at an idle. Seems to run normally at higher speeds and rpms. There is also an odd sound coming from the exhaust kinda like a popping sound not smooth. I've had the car three years and it always ran great. This just started two days ago.

 

Check for a miss, and you may want to say the year and model so that we can better guide you.

 

The year is 94 and its an se model.

 

While the car is running disconnect the coils 1 at a time to see which one DOESN'T affect the idle.
