Group, We have a '94 T-Bird with the FI SOHC 4.6L V-8 with an automatic transmission. Oft time there will be a groaning or moaning type noise that seems to come from the right front engine compartment whether driving or at idle at a stoplight or intersection. Could the MAP sensor behind the airbox be the source?
It also runs rough both at idle and on the road. On the road it hesitates and misses and will not accelerate as it should. When the car runs good it will press us back into the seats as it accelerates. I tried changing the fuel filter but cannot disconnect the outflow line. Is there an internal snap ring?
We need for it to last about another year so any help will be greatly appreciated. Thanks!
