ok i searched the forum and did everything i could to try and solve this issue. im getting a misfire in cyl 5 and cyl 6 only at WOT but i do not feel the misfire or loss of power at all not one bit. once i see the cel blink i hook up my vagcom and its always cyl 5 that misfires first and thats the only one that comes up then if i drive a little more it misfires again then it says cyl 5 and 6 are misfiring.

have a b6 3.0

i changed my plugs twice
all new coil packs
took my PCV system out and cleaned it all out no cracks found.
replaces all my vacuum hoses from the plastic ones to all rubber ones.
all vacuum check valves seem to be ok
switched injectors around to different cylinders and the misfires stayed in cyl 5 and cyl 6
all the o-rings seem to be good in the injectors.
just replaces my CPS (speed sensor) yesterday
new fuel filter

i do have an exhaust leak on the passenger side on the down pipe near the 3 bolt flange getting that fixed monday dont know if its related.

my rosstech reads
random multiple misfire
misfire in cyl 5
misfire in cyl 6


also i have a crazy hard time starting my car it does start but sometimes it actually locks up and doesnt rotate the flex plate, it sounds terrible when starting like im trying to start my car with open headers its so loud
