Knock in gears 3-6th, a common problem?

[SPEED3TYPE2]

that should have nothing to do with the blown motors. if the fuel pump cant keep up the car will trigger fuel cut. my car is one of those affected with the weak pump. i always got cut when the pump ran out of steam. and as for the ms6 blowing the motor, i blame a bad knock sensor. these cars should never detonate to the point that you can hear it. the knock sensor is supposed to detect it long before that and pull timing to avoid a problem. my car pulls timing all the time because of knock. thats what it is supposed to do.

yeah that makes sense boost spike from mazdaspeed cia cuases fuel cut if the snesor is working properly if not ping-boom.. I got alot of fuel cut after installing my mazda cia in the upper gears this is what he got.. but instead of fuel cut..ping-boom
