While accelerating to enter the highway a loud pop sound was heard and the engine lost power. I had enough speed to make the break-down lane. The sound was coming from the #3 cylinder on the right side of the motor. 4. 6l v8. These were factory plugs and the vehicle is maintained every 3000-5000 miles.

Driving on a posted 40 mph county road approaching a stop sign. The vehicle made a loud noise from the engine compartment and lost 80% power. Took it to a local mechanic and they explained that the spark plug(s) were bad and the tune up would be $500-$800 depending on "if" one or all of them broke during removal. One had already blown out during aforementioned incident. I understand that this was a problem for a lot of Ford vehicles during the years 2004 thru 2008. I believe this should have been a recall repair. Thank you.
