So I’ve been occasionally blowing my ignition 20amp fuse on my ls swapped 240sx. Recently I was backing up and it popped, replaced it and ever since it’s ran on just my driver side cylinders. Unplugging maf/tps/iac/passenger side changes nothing when it’s on. Grounds are good, no visible melted 02s but I haven’t replaced them yet. It appears thru my scanner that my bank 2 sensor 1 doesn’t have correct voltage. I’m thinking this might be it but I don’t get why I keep popping fuses in reverse and also I didn’t think a bad 02 would make it run this bad. Any ideas?
