The fuel injectors may need cleaning,or replaced,and if you havent changed the plugs may be time to do so.

Mark are you familiar with the 2001 mercury cougars 2.5 v6 dohc fuel system problems including MAS-fuel pressure senser-ect. I seen on another site a few weeks ago where people were having the same type problems but cant remember all the things they said it could be. while parked it will take gas up to about 2500 rpm but the more gas you give it makes itboog down and eventually quit.Thanks for any input you may have.....ANY...lol
Yes ,i familuar with the fuel system,the only other thing you might check would be the fuel pressure regulator on the fuel rail,
