2006 Ford Expedition Limited 4dr SUV (5.4L 8cyl 4A)
This is the worse SUV I have owned, I have to replace a coil every 2-3 months, it stalls sometime when driving. The factory spark plugs breaks off in the head of the motor, costing $300 to $2500 to replace, you have to remove the motor head, sometime the motor to remove the broken plug. Ford should have recalled the cars, trucks, and suvs thats having these problems.
This is not true.
Problem with the plugs do not require head removal. Yes the plugs are flawed , but only on the 3 valve 5.4 V8 , but with propper care they can be replaced easily withou breaking it.
Problems with coils was kind of your own fault , one goes bad, replaced them all at once, not only the ones that went bad.
I have done the plugs on my 5.4 V8
in less than one hour , without breaking any.
Please do not generalize ALL Expeditons are bad .
