Hello all, my focus started misfiring intermittently under WOT this past week. It’s tuned by edge and usually runs on the e30 tune. This past week it started misfiring under heavy acceleration, but drives normal when driving normally. I replaced the purge valve a little over a year ago. Car has 108,000 miles on it. I ordered new ngk ruthenium plugs and am waiting on them to arrive. Just as I got home I got a check engine light. The codes are P0088, P1450, and P2196. Does anyone have any ideas as to what I need to replace/address to fix these codes? Thank you for any help/input!
