My knock sensor broke a couple weeks ago and I cant stand driving my car with retarded timing. I was just wonder if I should try to get one from the want ads. Or if it is justbest to buy it new? Thank

either way will work, if it is a inexpensive part and the dealer has it I would just get one from them. Hurry.............they close early on Saturday. :)

I got one pretty cheap on ebay.

Thank You
