2003 Crown Vic PI
Sometime it feels like the idle skips a beat. I can feel vibrations under my feet. This morning when I pulled up at home the idle was loud (high) and my check enging light came on. However, it went off after it sat. Thanks |

Go get a parts house like O'Reilly's, Autozone, or Advance Auto to pull a code if you don't have a OBD scanner. Once you find out what may be wrong, then you can start fixing it.

+ 1 on the codes it will still pull codes even if the light is not on
If you find it is a misfire on say number one move the coil to a different cylinder and see if the error code moves that will tell you it is a coil pack issue. If you move and it does not follow you will want to pull the plug and inspect it to see if you have a coolant leak or mixture issue. If it looks good change the plug.
Usually with the coil on plug motors like ours you will need to change the coils every 80-100k. |
