Hey people, my 240 runs great except this one little issue I've been having for awhile now.

It studders a little bit at idle and a little bit more right when I give it some gas, like right off of the line for instance. Other than that it runs great. I checked my ecu for the codes and I got code 34 which is the knock sensor. I don't see how that could make it studder like it is, but I thought I'd ask all of you other 240 guru's.

BTW, I checked my plugs, timing, plug wires, cap, rotor, changed the fuel filter, made sure all of my vacuum lines were tight and not cracked, I even replaced 90 percent of the vacuum hoses, I also replaced my EGR valve PCV valve, and the BPT valve just because they were old anyways. I cleaned out my IACV too... I donno guys I'm lost now.
