Engine stalling at red lights intermittent. no engine light. in town. no power steering almost cause accident. this has happened several times.
While in motion traveling down highway i heard a bang and the engine began to knock and a sound of air was coming from engine and lost horse-power. i found the spark plug blew out of the #3 cylinder. i had to repair, and now the plug has dropped down, may have to spend up to $3,000 to repair/replace aluminum heads.
Van had trouble starting so took it to dealer, thinking it might be plug/injector-related. shop contact indicated leak in fuel rail, dumping gas onto engine potentially resulting something that could ignite and explode. the 2007 series 150/250/350 with the large 5.4 (?)l v-8 already has a recall for this exact issue. thought it would be wise to point out same problem with my with the 4.6l v-8. van has ~43k miles.
Spark plugs are breaking during replacement. bad spark plug design, spark plugs cause running issues, if they break- and fall into the cylinder- then it becomes an even more expensive repair. a definite flaw on ford's part. *tr
