I am about ready to burn my 2002 taurus ses to the ground. I have 68 000 miles. about a month ago it started to loose power big time. it feels like you are trying to tow a tractor trailer with it. I checked fuel pressure it was low when it primed and low when it was running, as well the pressure would drop to zero with in 30 seconds of turning the key off. so I changed the fuel pump and filter. I had changed the filter about a month before but still changed it when I changed the pump. the only way I can drive it is to lightly touch the gas if I give it much it just struggles to go. no sputtering or hitching it feels like it just can't go. Also when I do try to acclerate hard it just struggles and slowly picks up but will not shift a gear until I let off it well continue to rev til it hits redline I'm sure. but its not slipping its messed up I don't even know where to begin any help would be great
