Anyone gotten check engine light code 43 yet? if so, what did you do?

Yeah, it's primary coil #1. Check your coil wires/connector. If it looks secure, then it might be your coil pack. You can check the coil pack by unplugging the connector to the coil pack and measure the resistance between pins #1&2, then pin #2&3. I think it should be about 50 ohms. If it's too much more or less, then it might be bad. Also, check your plugs.

I've got the same code Paul. No problems, but then again, I'm not running any boost. :P How old is your MSD coil now? Maybe it's time to look into something more adjustable?

my msd coil and wires are a little over a year old and plugs are a week old. i just did the test on my coil and that was good. could it be the harness? but if that, how do you change the harness? it's connected to the main connectors. splice it in?

You might try peeling back the insulation on that wire loom that goes around the harness back there. I've heard of some Neons getting the wires frayed and then getting really random misfires because of that. Just a thought.
