Some friends believe its fuel or ignition but then everything is new (bbk 255lph fuel pump, fuel filter, NGK iridium spark plugs, MSD plug wires, remaned distributor and MSD cap and rotor). Ive checked fuel pressure and it was fine, cleaned the mass air and throttle body and it still does it. Before I took it into the shop to get the coolant leak fixed it would go to "redline" with no cutting out or hesitation but the only thing that was replaced in the ignition at the time was the distributor (buzzing sound). When I found my coolant leak it ended up being a cracked head so I got 2 used heads but they were non emissions heads. Ford said they could install them and would remove my emissions but couldnt pass inspection afterwards. Anyone have any ideas? ive tried explaining EVERYTHING possible</p></blockquote><p></p>
