"Stumped, problem has persisit
"Stumped, problem has persisited for 2 years now. Engines start and run normal. After some time at cruise 3400 RPM's, start losing RPMS, starts surging. Then if I don't throttle back, she chokes all the way to idle. Will run 2600-2700 all day but not full throttle. They are 454 crusader XLI's EFI's new plugs and cap and rotor, all new colling components as well. The engine that this is happening on has 80 hours. Changed the racor filter as well."
