3800 series 2, when you press gas to halfway point it slows down like you took your foot off, release a little and it goes again, push it past halfway and it picks up. It has power, just bad at halfway. Replaced the gas tank, sending unit and fuel pump, fuel filter, fuel pressure regulator. The car also has all new sensors including EGR valve, 02 sensors and all of the sensors on the throttle body. New timing chain and gears, complete exhaust, complete ignition with coils, module, plugs, wires cam and crank sensors. The upper intake manifold is new and the lower intake gaskets, idles beautiful, no skips, no overheat, no check engine light yet still has same problem.
it is a project car, being restored to like new again so I am throwing parts at it. The engine only has that one issue. Also, the code was relearned a while back. Tremendous pickup up until halfway and after halfway when I hit passing gear.
have the same problem?
