    knock sensor? or bigger problems?

    So my car threw a knock sensor code on me a couple weeks ago. Got out my trusty OBDII tool and cleared it. I had noticed a slight skip, and since I've only had the car a month or so, I decided to go ahead with a plug/wire change. Did that, and a few days later the code came back up. It seems to clear for a few days at a time, and the car runs fine until the code pops and it retards the daylights out of the ignition. I brought it to a mechanic friend of mine, and he noticed a slight knock, nothing really loud, in fact it took me a while to hear it when he pointed it out and also a slight vibration at about 2200rpm. I know these cars have always had loud valvetrains, but he seemed to think it is a wrist pin. My dad has been a mechanic for 40 years, and he listened to it before I brought it to the shop, and didn't hear it. Anyone have a clue? I'm really not enthused about tearing the engine down, but I want my car to run right.
