Me? I'll be doing a tune up on the Camry. Try to get rid of that pesky misfire that's getting worse.

Turns out it wasn't the loose ground. Or maybe the loose ground led to the problem... somehow. All I knows is, the wires look original, there's no clue as to how old the back 3 plugs are, and there's a small oil leak back there that needs fixin' anyways. Might as well pull the intake of and do it all. And a PCV valve, for good measure.

There's $100 and a night after work down the drain....
