Question about 2001 Mercury Sable
2002 Sable LS 43,000 miles. Check Engine light on again, just replaced the bad ignition coil and wires and plugs 6 months ago. there are no performance effects yet. have refilled the gas tank 5 times since light came on... Help
I have an '01 Sable that posted a Check Engine light and the problem turned out to be a Mass Airflow Sensor.

Tips for a great answer:
1.Fuel injectors, related wiring, sensors, computer issues
2. Running out of gas, or poor fuel quality
3. Evaporative emissions system (EVAP) concerns: fuel vapors leaking into engine
4. Incorrect Fuel Pressure
5. EGR system concerns: leaking EGR valve or restricted ports
6.Base engine concerns: low compression, valve train problems and timing issues
7. Ignition system concerns including, but not limited to:
Faulty spark plugs
Faulty coil or related wiring
Ignition module or related wiring issues
Ignition related sensor faults or wiring issues
You will have diagnose each element until you find root cause.
And it could be more than one element faulting out.
