switch the amplifiers on top of the airbox and see if they move to cyl 1,2,3.

Default try what he said...if you continue to experience the same issue

check all plugs (if you havent changed them in the last 40K miles, they do need to be replaced). If that doesnt solve your problem, talk to Bruck. I think he experienced the same issue and might be able to give you more info.

Default well, if you've changed plugs, amplifiers, wires, and coil-packs -- seems to me that it's most

likely a head problem. might do a leakdown test if the misfires are numerous enough. How many are you logging in a minute? Are they only at idle?

Default Bruck is his AW screen name...search for it. He had a lot of misfires issues

AOA ended up replacing his heads to fix the issue.
