temp sensor under manifold and plug
fuel pressure regulator replaced with a brand new one - no difference

checked injectors and tested in and out of car, under pressuremchecked wiring between all sensors and injectors ecu plug all came up good after changing the TPS plug
swapped out the airflow meter with a known working one from neighbors car - still the same result
****** replaced injectors still same result ******
