350 Chevrolet 84 Corvette misfires when hot?

[tjs1139]

I have an 84 Corvette that seems to run fine when cold but when it reaches operating temperature it runs rough and loses power. It was just rebuilt and may have had the problem before but it was always oil fouling plugs then. I have no ECM codes set and already replaced the ignition coil. I double checked the valve adjustment also. Any ideas?
Car has dual single barrel throttle body injection. The fuel spray out of the injectors looks fine.

what about the wires, did you replace them with the plugs. you could possibly have a leaking spark. try this, get it warm pop the hood. take a spray bottle with water, and aply a very fine mist to the wires and listen, if you hear a change then the plug wires are shorting out to the block. replace and enjoy.

sounds fuel related, check the fuel pressure, when it is hot.
Also would need for information on your carb or injectors on this vehicle.

the problem is in the distributor
