so after replacing the plug with a motor craft i turned it on one morning and the check engine light went off so i think it fixed it the weird thing about my car is even with a mis fire you really cant feel it like ive had cars with misfires and you could tell but this one you really couldnt so idk if its fixed or not but ill prolly put a new ignition coil just to be and check the new plug for oil or coolant in a couple of days
