Need Help Please!!! My knock sensor is bad well thats what the code reads(P0332) at the same time if im on the streets going about 40mph its ok, but once im on the freeway going about 65 and over the service engine light starts blinking 
. So then i get home and read another code it reads (P0300)something about random/multiple cylinder misfire. This only happens after 65mph. Will that be caused by the knock sensor??? Another thing if I were to run it at WOT once i let off the throttle the car seems like if it chokes, then it backfires and the motor cuts off,so i have to pull over and start the motor again. CAN SOMEONE PLEASE GIVE ME SOME POINTERS??ANYONE had the same problem b4???

if your check engine light flashes that means your catalytic converters are in serious danger of getting damaged usually due to a bad misfire(p0300). you should check the misfire counter on the scanner to see just how random that miss is. there is usually one primary misfiring cylinder and it causes others to do the same.once you find it concentrate on that cylinder and you should be fine. the knock sensor shouldn't cause anything like that just set a code.
