Same issue bucks and check engine light replaced three coils and after a day it progressively got worse this time we received no codes, finally replaced all the coils and a vacuum line from the master cylinder and it seems everything has come back to the norm with a definite improvement in fuel mileage first road test was 200 miles towing another vehicle and no issues bottom line i suggest replacing all coils at the same time
