Car starts and run but will fire occasionally with throttle closed but wont get running unless the throttle is being feathered. Car idles great once running
any idea what the issue might be? the car also runs like dog shit when you put it under load or rev the engine

Has a brand new knock sensor and 02 sensor.
unplugged maf and car dies and wont start til its plugged back in.
unplugged the red coolant sensor and the car stuttered a little and kept idling
unplugged tps nothing changed
unplugged knock sensor, no change
fuel pressure tested at 40psi at idle and 47 while the pump was priming

i tried advancing the timing run kinda shitty, then retarded it and it didnt want to run

could this be a fuel injector issue? i tested them all with a 9v and a voltmeter ea clicked open and tested at about 10.8ohms which is right where they should be

could my ecu be the problem? or even a collant temp sensor?
