I have an MSD Pro Billet distributor and every now and again if the car runs hot for whatever reason the idle gets all messed up. it idles rough and when I get on it it seems to ping under heavy load. I suspect when the motor runs hot like that it changes the timing curve. Maybe, the springs inside the Pro Billet get weird...

does this make sense or am I way off base?
