1. My distributor sounds like it has a small pebble rolling/bouncing around in it at cold startups but goes away after 30 seconds or so. It's an MSD distributor with MSD blaster coil.

2. The car sputters/missfires slightly at light throttle (when cold) for the first few miles but gets better as the engine gets warmer. It also has light random missfires at idle when it's cold which again goes away when the engine is warm.

B18B, stock internals, 7psi, 440cc injectors, walboro fuel pump. If you need any more info than that don't hesitate to ask. I know the plugs could stand to be changed which will be done tomorrow, but assuming it doesn't help the problems, what do you guys think it is?

 

Anyone? I need to know if it's my spark plug wires or the blast coil itself. I changed the spark plugs and gapped them perfectly and everything.
