Default Misfire
2008 chevy impala ss 5.3L v8, misses after warming up, no code, lifters have just been replaced and valves reseated. New coils and plugs and wires all around. Large random spark between coil mounting plate on right bank and valve cover bolt. Same left bank but much smaller and less frequent. Any ideas?

Holy crap X2 on this.

The voltage is trying to get back to ground and it will...somehow.

Voltage is very lazy....but it is also very strong.
