I have a 1998 ford expedition.A few months ago it would run rough and the check engine light would come on. This problem was intermittent though. Now its constant. The trouble codes read misfire on cylinders 3 and 8. Replaced the spark plugs and wires. No difference…the spark to those cylinders seems strong and consistant. Any ideas. Thank you.
have the same problem?
