update, I replaced the coolant temperature sensor with one from a 91 240sx because I read that was a suitable replacement idk if right or wrong. The idle is still high but now the car is running lean instead of rich. I also cleaned the maf, could be what made it read lean? I really don't know what to try next. If the AFR was solid I would just adjust the idle set screw and call it a day but it was too high now too low. The fuel pressure regulator seemed ok as well. I'm in socal so i dont really need the cold start wax element thing. Woe is me
