Remove the vacuum hose of the fuel regulator, if you see or smell fuel replace it.

Fuel regulator ok did not see or smell gas from the regulator. map sensor and throttle position sensor replaced also.Could this be a vacuum leak problem, maybe when vaccume hose gets hot it expands and leaks?

Yes me to although I did a fuel injection service at a shop, this is where the send the injection cleaner directly through the carb. When I replaced the plugs as I remember there was 1 plug that did look a little smutty. Is there a way of pressure blowing out the injectors and is this expensive, Can a injector expand with heat and cause problems when it gets hot. Does and injector usually get stopped up or does it just go bad on most vehicles . If so with this many miles I may just drive it until is stops then put a lower millage motor in it.

Excess fuel will run good with a cold engine, not so good hot. I would say the sooty plug has the bad injector.
