Recently had my air oil seperator replaced. At start ran a little rough now runs super rough and wants to stall. Changed 2 pre cat o2 sensors and mass air flow sensor. These are the current codes, 0112, 0300, 0301, 0302, 0303, 1316, 0102, 0130. Prior the car ran perfect and I cant believe I have all those cylinders misfiring because of plugs or coils. Please help
