Alright,
My car ran like like complete crap this morning and so I checked my codes and sure enough, codes 31 and 52 were logged. 31, which I believe is the afm, which I replaced a few months ago and has been serving me well and 52, which looks like the knock sensors. My question is how can this afm go bad already?? Also, 52 seems to be quite random, and I can go many months without getting a cel for it. So, what do I need to test the afm/knock sensors, multi-meter? and what should the specs be? By the way, once I cleared the codes the car seemed to run just fine, my assumption is that by erasing the codes takes the ecu out of whatever crappy mode it was running in. LMK
