Ok so I've taken a break from the Taurus as it was driving me nuts lol. So I'm back at it, though I am yet to change the MAF (my next step today) I noticed something I had not before. The car seems to be running fine in the park position, I can rev up to high RPM's and nothing unusual. Soon as the car is out into drive it starts to bog and can't give any gas without it wanting to stall. Once I put the car back into park it will catch itself and I can again rev it up. Any ideas?? Or do you think this could be the MAF doing this?? Ps, all O2 sensors have been changed and so far no lights on dash.
