2004 Mercury Sable random misfire
I have a 2004 Sable. The other day my car started shaking a lot and the check engine light started flashing. Took it to autozone they said I had a misfire on 6. I switched the coils on 6 and 4 and took it back, the misfire was now on 4. Bought a new coil and replaced the coil on 4. Ran ok for a few miles, then the same problem happened again. Took it back to autozone, now the misfire is still on 4 (the brand new coil). Now the check engine light is steady on and it's running worse than ever. Did they sell me a bad coil? Why else would the misfire haved moved?
