backfireing and stalling out. I just replaced the injectors in the Carb. checked the egr valve. replaced the carb harness. cleaned the O2 sensor. yeah all of that. now she backfires and stalls out almost dying when i push on the gas a little bit. I think it might be a bad fuel pump, filter, or line but i'm not sure. is there anything anyone can think of that might cause that to happen?? She runs fine when she's idleing but whenever i put her in gear and try to move she backfires stalls out or dies.
