Hey guys. Ever since I have owned my car it has had a slight mis at idle. its just a small poping noise in the exhaust. It gets worse when i turn the AC on and it has been getting worse lately. I have new plugs, coil packs, and even tried new injectors. Im getting a fuel filter today to try. Does anyone know if this is a frequent problem or know how I can solve it.. Its really starting to irritate me.

Thanks

You say coil packs, so I assume you are a 96-98 mustang. If that is the case, the next step would be to check the plug wires.

Any codes? Are all of the coils replaced? Check the first cylinder on the drivers side, see if there is coolant on top of the spark plug.
