been tuning lnf's for a while but havent seen this issue before.....
cylinder compression/leak test all pass
move the coild packs around and the same cylinders are doing this problem.
i have a constant kr in the mid range...it never goes away even when i remove up to 10* from all the value areas......it seems to register mostly on cylinder 4 but have seen on cyl 2 and small amount on 1. can clutch trans noise be causing my issue.....? any other ideas to check?
