You know what, my plugs actually are really fouled with carbon. But they only have i'd say about less than 10 miles on them. Could just changing them to new plugs hopefully correct the problem? How would i go about cleaning them? I know there are "spark plug cleaners" but is there a method i could use with basic tools? Could i just go about wiping them with a towel? Ha. Thanks! If the plugs are the culprit i sure hope it fixes the problem. How does my AFM measurements look? Also just to note, i started to inspect the engine bay more closely and noticed the hose for the PCV valve was horrible, it has a crack at the end that goes into the PCV valve and seems to be wrapped with foil, then electrical tape.. sigh. I guess i'll be replacing that too, now would i have to get a 280z specific PCV hose? because it has a bend to it, or i'll be fine with just some normal 5/8 hose from the parts house? Thank you all in advance. Picture of the hose

Okay, so i attempted to get my car smogged but the CO and HC were ridiculously high, from running rich. Drove it home and just started looking around the engine bay and i saw that the Water Temp Sensor was unplugged! It was missing the connector and all, the 2 black bullet connector wires for the sensor were just dangling around the engine bay, how didn't i notice that before? ugh. Well i'm PRETTY sure they are for the water temp sensor, anyways i bought a connector and a new sensor it was fairly cheap and figured why not, I wired it up and when i connect the sensor the engine idles super rough and if i were to give it some gas it'd just die. If i unplug the sensor, it runs OK. but still running rich, i noticed that even when it's plugged in i don't smell the excess fuel anymore but unplugged i can smell it. Any insight on this? I've also measured the AFM: i referred to the EFI bible pages (49-51) Okay, the measurement #1 was pins 6 & 8 now this was from the ECU plug( All three measurements were) which was 321 Ohms the EFI bible says measurement should be at approxiamtely 180 Ohms so.. that is definately not righ?, measurement #2 which is pins 7 & 8 257 Ohms EFI states should read (Continuity, small resistance) measurement #3 Pins 8-9 measured 145 Ohms EFI bable states should read approximately 100 Ohms. I haven't actually measured from the AFM itself but i did clean out the flap which Air flow Meter Cleaner.
