I have checked the fuel pressure in the past. It's a shame that they didn't provide a fuel pressure test port. Item seems like the auto enrich feature is not working. Either the MAP sensor is feeding the ECU bad tem and airflow readings. Or, the O2 sensor has leaned out the fuel trim so much the the close loop starting fuel trim has been modified. I don't suspect a throttle position sensor issue.
