My 96 Maxima with 115,000 miles started stuttering and shaking one day, and when I stopped it acted like it was going to stall. I drove for another minute and it stopped. Since then, for the past week, it has happened 3 more times and stalled out once. I hooked up the OBDII computer and it gave me this: P0732 Gear 2 Incorrect Ratio and P0325 Knock Sensor 1 Circuit Malfuntion
Can anyone tell me what this means. Do I need to go ahead and replace the knock sensor or do you think the other problem could've caused the circuit malfuntion? Thanks for any input
