the past day or so i have noticed something very strange. while im driving the '96 900se, i wind the engine up during hard accelerations, and the motor stops pulling at about between 5000 rpm, and redline, it randomly varies. i installed a mbc a while back and its been working perfectly, and i know its not reaching the fuel cut off. its not just cutting power, it just slowly stops pulling, but remainds cranking at that rpm, it feels almost like it gets stuck or something. its hard to explain. its also been pretty hot out latley and maybe its due to lack of boost? the mcb is set to my cool weather settings. or can it be an ecu problem? i dont know for sure.
