well here is the latest update from my horrifying adventure.
both sensors have been replaced by the standard part number AF sensors that were suggested, and i had to completely rewire the sensors myself with brand new wiring and brand new relay. (previous owner did SOMETHING crazy with the wiring, possibly to make it work with a regular 02 sensor)
also two brown ground wires from the ECU, known as "E04" and "E05" were cut, so i regrounded them. all wiring tested, all grounds tested, all confirmed fine.
then p0171 was joined by p0300. i braught the vehicle to a professional shop and they decided "if we disconect the throttle body sensor, the car wont throw p0171 or any other codes, but once we reconect it, the codes occur". therefore i was told to replace this sensor. i just did so, apparently my sensor was out dated, part number ending with 06020 or something, when the new one ends with 33030. i dont know what they did at the shop but now im giving black smoke instead of white smoke, which means im running super rich.
so now with the new sensor, and having spent tons of money, the problem PERSISTS.
p1130 and p1150 happen intermitently, not consistent as before. p0171 is CONSTANTLY nagging, and im blowing black smoke, running a little low idle and a little rough, hesitant.
im about ready to throw in the towel and put this thing away for the winter. my soul is tired.![Sad](https://www.clublexus.com/forums/images/smilies/sad.gif)
