If the MAP is clogged it will be allowing more fuel. Scan the motor while running to see what its showing

Too high fuel pressure will cause it to run rich. I'm not familiar with how that fuel system is setup.

Also agree to check map sensor. Scanning it would be the best so you can see what all the sensors are doing. You might have an issue with the sensor 5v wire or sensor ground.

I appreciate all you guys giving me ideas. I’ll get busy first with fuel pressure. It has a new MAP sensor Along with most other sensors all replaced too. I’m thinking fuel pressure might be the answer. Thank. You guys. And I’ll try 89 octane too
