I was sold this vehicle privately, on the impression that the seller had tried to remedy a shuttering problem when the vehicle reached 80km/h. He thought it was a fuel pump and had it replaced.

When I first took the vehicle on the entrance ramp onto the highway I found it shuttered at 80km/h. Obviously this is a potential disaster considering my inability to accelerate up to highway speeds in a quick and efficient manner. I was only able to accelerate up to 100km/h after taking my foot off of the accelerator and very slowly pushing the accelerator back down occasionally feeling the shutter. When I have the cruise control on, the engine will shutter when I am going up hill. I have received a quote to replace my sparks plugs which my mechanic says "might" fix this, at a staggering cost of a minimum $500, plus $80 for each broken spark plug. He informed me that these spark plugs are a major pain in his ass to remove and could possibly break off causing catastrophic damage to god knows what else in my engine. Mind you I have just handed over $300 for what was thought to be the cause of flushing the transmission fluid and adding some conditioner.

Now I know vehicles are a money pit, always have been, but this particular problem seems a little too common to be a coincidence. Lets be honest, these spark plugs are a horrible design to an otherwise fantastic vehicle. If Ford cannot admit to this flaw, they have lost my confidence in their ability to stand by their product. They make vehicles and if they make mistakes making those vehicles, people lives are at stake. This isn't pillow making, basket weaving or tennis rackets we're talking about, these are hundreds of pounds of steel carrying the people we love around at high speeds. There isn't room for this kind of error to just be overlooked, this is serious, and it needs to be addressed A.S.A.F'n.P.
