Fuel Issue
98 3.0L XLT. 141K. Starts right up. Rough idle.
Bucking and losing power under a load. Primed pump 55PSI but leaks down slowly. Running I get 65 PSI and then also leaks down. Been hearing about check valve but cannot find the part anywhere. Doesn't look like any check valve shown on the fuel pump diagrams. Regulator ?
Injectors ? Have already thrown an idle air control valve at it. Can anyone help out. Thanks
