Hi Guys,

My brother's 99 TA has 64K miles and we changed the plugs 1 month to NGK TR-55's gapped @ .055 and changed the fuel filter as well. I had a MTI B1 cam put in it 221/221 .558/.558 114lsa and brand new 2002 LS6 cam springs with stock retainers and stock pushrods and it has a P0308 cylinder 8 misfire code now. I know cams usually cause a P0300 random misfire code but this one is specific to one cylinder.

Any ideas on what to look for guys?

Thanks
