I am having issues with a cel and miss on 3 and 5. Ive swapped injectors and cop the only thing i can find that tie 3 and 5 is they are on the upstroke together. It does not matter the tune it does it under hard driving. Its cat delete cel antifouler 2018 intake blackhawk k&n cai. Bama tune. Ikik bama yuk on a budget. Want to fix before i go e85 and pro tune. Please anyhelp would be appreciated.
