So, when starting the car with a hot engine - for example you drive to the store and pick up something in 5 minutes and then back to the car - my engine sometimes misfires. Not running on all 8. It sounds like it has a big cam (it actually sounds really cool) and the exhaust smells of raw gasoline. If I then turn it off and immediately back on it goes away. Plugs are fresh, wires seated firm, no vacuum leaks (to my knowledge). What would be your best guess? It's clearly ignition related.

 

The ignition control module and pickup coil would be my first suspects. start drilling down the ignition components starting with cap and rotor, get the ICM tested or swap it, check the condition of the pickup coil, the pigtail wires and coil itself can get very corroded and essentially fall apart.

 

I'll check the distributor one extra time. But, what boggels me is that the problem only occurs when starting a hot engine, never a cold.
