error code 43 Multiple/ single cylinder misfire
I have a 1999 Dodge Neon. The check engine light keeps coming on with the error code 43 Multiple/ single cylinder misfire. I've changed the plugs and wires but the same error
occurs occasionally. When it first starts is the time the error may occur. After it warms up, the error doesn't happen as much. I have no idea what the problem is. Does any body know what would cause the 43 Multiple/ single cylinder misfire ?

Most likely you have an issue with the ignition module or the coil. It may be as simple as a bad ground. The code you mention is missing a few characters though.

Code 43 is the old numbering system. It can mean either a Random cylinder, or a specific cylinder. The 1999 model is OBDII compliant and with a scan tool you will get a 4 digit P code. This code will be more specific. Proper diagnosis will be possible once you have this P code. Go to a local Advance or Auto Zone they will pull the codes for you for free. Dont let them sell you anything. Post the results here and we can proceed.
Hope this helps ya,

Wouldn't hurt to begin with starting it cold when it's dark outside and see if you can see any visual signs of an ignition problem, i.e. a plug wire shorting to ground.
It's old enough for any of the possible causes in bob's link to come into play.
