Rough Start - Something Seems Wrong

Just another possible source...
Toyota Tacoma with 242k miles has same issue. Need to pop the hood and let it cool for about 15minutes to get it to start. Z seems to retain heat in the engine compartment way better than the Tacoma since the Z's engine compartment is really packed. Haven't fixed it yet but the forums point to the:

Coil
Distributor
Air flow sensor
Air Filter Temp Sensor
Engine coolant sensor
Fuel Pump

Just mention it since the problem seems similar. My guess on mine is it's probably the coil getting old and breaking down slowly over the past 15 years. Just living with it for now since I have a work around (wait with the hood open until it cools down far enough to start)

For the Z, I'd look for anything with a self-resetting thermal fuse in it. Gets too hot and the component won't work till it cools off again. There's usually hysterysis in these fuses so it takes a cooler temp to reset them after they activate.
