welcome to strangeness
I've seen coil wires that only fail once it gets hot under the hood
I've had a miss that was random and it was a spark plug that had a small crack and the failure was inconsistent.
On the LT1, I've had the opti harness cause me grief, also an intermittant connection on the temp sensor (the one on the waterpump)
Since most of us haven't owned thse cars from the inception, you really have no clue as to past maintenance. So, as time moves on, you really need to repair/replace wiring and hoses and check your grounds.

I also pulled my air filter off today. I have a stock intake but it must be a factory performance intake because I dont have a square filter. Actually, my filter itself is K&n. I pulled it off and it was literally caked with dirt. Cleaned it with K&N's cleaning kit. My car runs so much better now.

I replaced the coil wire and cleaned my air filter. When she runs, she runs better, but still wont start when it gets hot. I used component freeze to cool off my opti and it started. So which opti should I get.
