i just pulled a knock sensor on my car for a check engine light thats on. 87k miles on the car, timing belt is said to be replaced at 105k. i thought maybe a slippin timing belt would throw this code. also my ignition coil is gonna be replaced tomorrow. will that help with my dogging acceleration problem? any thoughts on this knock sensor code and how to fix it and if my coil is whats causing the doggin. the wires and plugs have been replaced though. thanks
