Ignition breaking up under load
I have a MSD Ready-To-Run and Blaster 2 coil. The RTR is about three years old and has 3-4k miles on it.
The ignition is breaking up under heavy acceleration at the bottom of second. It's fine under normal driving or even heavy acceleration in high gear.
I replaced the coil, plugs, and wires. The cap and rotor look good. So, I think I've isolated the problem to the module.
I recently tack welded part of the exhaust, and I forgot to disconnect the battery. I did not disconnect the distributor. I don't think there was a problem before this. Did I damage the module?
I have an email into MSD tech, but wanted to get an opinion here.
