my lincoln loses power when under load,ive put new spark plugs in and a new fuel filter. I had a diagnostic done and that reveled some air leaks.Behind the rear wheel there are 2 pipes,they come from a black box at the rear of the car and 1 goes to the fuel tank,the other goes nowhere,should that 1 be blanked off or should it be connected to somthing.
