Sounds like it could be a bad/loose spark plug connector ? are all your plug wires still held place in with the plastic loom clips?
If it's not something simple like that then it's likely a wiring harness connector/wire end loose.
I'd let the car idle and start jiggling wires (on the left side) gently to see if it can be induced to miss after checking to make sure all the plug connectors are tight first and the boots pushed in snuggly. Also gently jiggle the wiring harness connections on the coils.
Let us know if you find something.
