picked up myself a ae82 with a 4agze conversion a month back, was going sweet until half way to work one day and it started the sound like a lawn mower. still runs but sounds like running on only 2-3 cylinders and fuel is leaking straight out of the flange between the headers and exhaust.

couple of mates think its injector problem of maybe an ecu problem.

just wanna know if anyone has any ideas as to what the problem could be?
