im thinking its a loose connection if your idle changes when you tap the ecu. Try taking it apart

to be honest its more of a bang than a tap(starting to get pissed with the car), but it still shouldn't do this. i've made sure the 10mm was tight and playing around with the wires doesn't cause a change. and a little more back ground info. the car started out with a slight miss(compared to the miss now, sounded like a wrx under load), so i removed the mafs and cleaned it, didn't really help. then i unplugged the mafs and started the car and gave it gas to keep it running, (i realize i should have had the car running and then unplugged it) that's when the misfire got really bad and made the car start to jerk at about 2500-3000rpms.
