Hello long time lurker here, over 4 years now finally made an account. I am at 86k Cobb stage 1 Injen intake. I started monitoring knock and misfire count after I put in new spark plugs. A code hasn’t been thrown but I’ll get misfires going to work (less than ten) ~10 miles of driving. Since a code hasn’t been thrown does that mean everything is okay? I thought misfire was a bad thing. Does anybody else get misfires read on ap but not have a code thrown?
