help w/ codes and surging upon accelleration
i just started experiencing some knocking while accellerating. the current pcm codes are p0410 & 0418(i installed headers and unhooked AIR), and p1652(induced chassis pitch output circuit). any ideas?

ttt ... these codes are most likely irrelevant to the engine hesitation, so can somebody give me a good place to start? i've heard clogged cats can cause surging but the cats are from a 2003 z06 (can't have that many miles?).. i figured if the MAF needed cleaning it would throw a code for it, as the same for bad 02 sensors.. now it is throwing a history code for the Intake Temp Sensor if i can recall correctly (i installed a twin cone intake).. i have yet to piddle with it, i was hoping somebody could lead me to a good starting point.. thanks!

i'm only posting this reply for anybody with similar symptoms who might run across this thread in a search.. i replaced my plugs and wires with ac delco irridiums and gmpp red wires from gene culley, bought some MAF cleaner and used it liberally, cleaned/ re-oiled my intake filters (twin cones), and used a dab of dielectric grease on all the electrical connections (plug-to-wire, wire-to-coil, MAF connector) .. i was kinda shocked to see that my old plugs (i'm assuming original oem) were significantly overgapped due to worn down electrodes, probably at least .060- .070.. i'm only at 56k miles.. anyways, i disconnected the battery and performed the idle relearn and did a quick test drive.. muuuuuch better maybe it's in my head, but seems like she even sounds meaner
