ok, the car is a 91 ef dx hatch with a obd1 converted ls swap in it. It throws no cel's. It is idiling very low around 300 and stallin out every once in a while,but it will jump up to normal 750-850 for a minute then go back to almost stalling. It runs like total crap at part throttle major hesistation like its not gettin enough gas. I pulled the plugs and its defintley running lean. I believe there is a problem with fuel delivery. The car has known good injectors we have tried a diffrent map sensor and ecu also none helped. What do u think this sounds like? I plan on checkin the main relay and fuel pressure next as soon as i get a gauge.
