2005 ford taurus
I have a 2005 ford taurus. Recently it would not go
faster than 20 MPH unless I have it floored. And
even once I get it past 20 it shakes really bad and
makes a horrible sound. Chamged the plugs and
wires thinking that would fix it but it didnt. The
mechanic said it sounds like a misfire on cylinder
1. Almost like it is stuck open. I really have no idea
what that means and I don't know how much it will
cost to fix it. What could be wrong?
