Subject: engine light
Sandy tells me: I have a 93 ford Taurus on Sun. the check engine light came on. Well today it came on again and then it started going off and on as the light would go off and on. I did not think I would get home and the exhaust really has a strong smell to it. I checked all fluids and all is good the power steering was a little low.
Sandy, the reason your exhaust smells strange is because the combustion in the engine is not complete for reasons only known to a diagnostic analyzer. In other words you need to have the trouble code traced and have the problem repaired.
The reason your “check engine” light comes on is because a component making your engine run properly is faulty or misadjusted. The computer on your car will “set” a trouble code to let you know which component has failed, or give a mechanic an idea of what to look for. The light will keep coming on until this is fixed.
You should check the fluids in your vehicle on a regular basis prior to any trouble to avoid just that.
Good job Sandy. Time to take it to the shop. 
Good luck…
Dave
