ok so i took the safc out and put the old intake mani on and it was running good until i turn down my block and all the sudden it started running like shit consistantly. it idles very low on 2 or 3 cyl all the way. not too sure what the problem is. when i disconnect the front and the rear coil pack and it shuts off. the 2 center coil packs when i unplug them it does nothing. so it must be those 2 cyl that are not firing correct? well then, i checked the plugs and they are fine, sprayed the 2 injectors with brake cleaner to see if there was a leak around the injector gasket and nothing happend. didnt make a difference. they are getting spark. it is getting fuel. all 4. so now im basically getting pissed. my boost gauge is staying around 0 and 5 fluctuating very fast. seems like a boost leak. ic piping clamps and couplers are all fine. lines from the actuator to the bov to the intake mani are fine. fpr to mani are fine. boost gauge to intake mani are fine. im basically getting fucking pissed so anyone have any ideas?

ok so i narrowed it down to an electrical issue. where can i go from there? and it is the back cylander cyl number 1. so what could i do? ecu related? ignitor chip related? fuel injector related?

tried swapping coil packs, injectors, the gasket that goes from the injector to the manifold everything. i get continuity and the right amount of resistance to each injector. please someone help me!
