More worrisome that the mounting of the coil. What brand of coil is that? Swap that out. These newer “trick” coils bring many driveability problems but they don’t quit they just cause trouble so you think it’s something else.

Do you have an aftermarket tach? Disconnect it from the negative side of the coil and see how it runs.

What are the 3 wires going to the left side coil terminal? Disconnect all the gadgets and see how the engine runs.
