Any chance someone can help me out on the specifics of this diagnostic code;
I have been experiencing hard starts for the past few weeks and today got a check engine electrical warning. I was able to retrieve the diagnostic code of P1386 which is listed as the knock control. I reset the code however, I'm sure I still have the same condition.

Specifically, what and where is the knock control?
Do I need to replace the knock sensors?

Thanks for any help.
