Default Weird Problem

My corvette c4 1994 consistently backfires and bogs down when running when i have all 8 injectors connected(mind you my fuel pressure is at around 35 at idle) but the second i unplug 4 of my injectors and leave 4 connected(disabling half of the engine basically) i can rev it freely without a single bog or backfire, Please help

Sounds like your injectors are sticking open. To confirm-Scan it-what are the BLMs? Any codes?

they usually stay around 128 but like to go up too 160 especially after revving the engine which makes me think the injectors are clogged causing an intermittent lean condition
