HELP; misfire on all four cylinder
I keep getting a check engine light stating that I'm misfiring on all four cylinders. My car drives fine though with no sign of it. I have an MSD 6al and SS blaster coil. I called MSD and asked if maybe I needed a tach adapter but the guy said it wasn't necessary. What are possible problems. I thought it could be ECU related or that maybe the plug wires I'm using could be interfering with it. Has this happened to anyone else?
