Thanks for the help guys. The code error was about plug 1. Changing the plug and wire didn’t help at first so I’ve added the new LiveWires and Screamin Deamon coil. No improvement. I still get an error code. I then changed all the plugs again(I’m using the recommended Champion Double Platinum Plugs). Seemed to work but once I took it out on a busy road the error message came back. I went with LiveWires recommended .065 gap. I’m going to switch them to the stock .050 gap and see if that improves anything. I’m wondering if the cracked stock manifold is causing the error code.
