Iso: I recently installed comps stage 2 cams and new lifter springs on my 2v, after installation i throw two codes. P0306 and p0316 . its saying i have a missfire in cylender 6. It keeps fouling. Ive changed plugs swapped around the cop, and fuel injectors, also checked compressio and its all fine. Car runs good and have a tune from sct. Any ideas? Thanks.

I'm assuming that there was no moisture in the spark plug well.
What were the results of the compression test (the amount of compression)?
Is the spark plug fouled with fuel or oil?
Since you have confirmed that the COP is likely good (by swapping) it's seems reasonable to confirm there is a firing pulse using a "noid" style test light.
