Intermitten stuttering

[silvercoupe97]

I've searched and found some that resembled my problem but with different circumstances. I feel that my problem lies in the stock fpr but I'm not sure...
So, I'm having a problem driving at highway speeds, my car starts to bog (not sure if this is the word I'm looking for) at around 3000-3100rpms, just as the turbo spools up and sometimes it happens while I'm trying to accelerate just a little (sometimes it doesn't). I notice that the front o2 drops to .12v (I don't have a rear o2) and I lose power but it will still accelerate at a very SLOW speed. It throws a random misfire code and once in a blue moon it throws a misfire in cylinder 3 and if I turn off the car and restart it, with the CEL light still on, it will run fine again until...well, whenever and if I get on it a little while it is sputtering/boggin, it will throw a knock code stating that I have a knock sensor malfunction (not often though). This only happens intermittenly. BTW, in town I'll drive her like I stole her and she's fine, on the interstate/highway is when it acts up (after I've been cruising for a bit).
I've checked for clogs in the filter with no luck there. I have new plugs and wires too. I'm stumped at this point and any input/advice/help will be very appreciated.

Well, I found one problem, it may be the only (ha) but it's narrowed down now. Oh yeah, it was the plug wires. It arcs onto my test light, just past the upper neck of the boot. I guess you can say that it leaks. So much for them being new....

Well, after fixing the arcing boots, it turns out not to be the problem causing me to run on three cylinders. It seems to have been that little power distribution thing that sits behind the rails and in front of the TB. It must have been loose or something.
