I'm new to this forum so I hope I'm going about this the right way. I have a 1993 s13 coupe ka24de 5speed. Recently, the idle was starting to act up and fluctuate. I've been busy so never got around to going with what usually occurs with that and clean out the iacv. I finally got around to it but by that time, the idle got worse but only when when I'm actually driving around. As soon as I'd get on the clutch, it would drop really low and then jump up and after a few seconds it would somewhat regulate itself but before I got around to cleaning the iacv, it was getting a misfire through low rpms but clears up around 2k and above. I checked for codes and I'm getting 12, 33, and 34. I cleaned out the iacv and the maf. Checked wires to the maf, o2 and knock sensor, they all seem fine. Anyone have any idea what's going on?
