Been having some trouble with one or more cylinders misfiring under load. Idle and light part throttle engine runs perfect. Compression and leakdown tests are good. Ford factory diagnostic tool doesn't find any misfire counts.
Running NGK TR6 plugs gapped at .037, they have about 25,000 on them and look good. The Whipple, mass air meter and injectors were put in at the same time as the plugs and have the same mileage on em. Car has about 95,000 miles on it.
Anyone have any ideas? Thanks.
