My computer crashed so I've been working on getting an old laptop back up and running to get me by.... that and I just can't ever seem to get any time away from work. I thought I had replied to you from my phone a couple days ago but I would have been working so I may have been side tracked.

You may have very well killed the AFM when you "cleaned" it. It's an optical type of sensor and the optics are VERY sensitive.

If you look in the MKIII FAQ section you should find a thread about the different diagnostic codes and another about the knock sensor or knock sensor rewire (related to code 52). If you don't see it in there then try searching "knock sensor rewire" in the MKIII forum.

Code 31 and 32 Air flow meter circuit or Vacuum sensor signal fault
Code 52, 53 and 55 Knock sensor fault

I have a new Toyota (stock) AFM if you are interested.
Complete assembly, used once for as a diagnostic source.

Thank you Cre for all the info and hints on where to look. This car has never really run right since day one. I know the previous owner(s) done a great job with the cars maintenance and upgrading as parts failed... but something is just not quite. Before i wrecked the afm the car had good and bad days... cooler nights I've been most impressed with the pull this car has... so I know what its capable of. Lol now if I could just see this consistantly

Thanks again for your time

Hello MJG, from what you described sounds like your offering the electronics and housing together. I appreciate you letting me know, but for now the best route for me is to try and find just the electronics...
thanks again

Yes, it is the complete AFM assembly. The electronic karman vortex generator was not sold separately from the AFM body, by Toyota.
Good luck.

Changed the afm, no more engine lights, car is running great other than me seeing the occasional puff off very stinky smoke... and its happening at the strangest times... when im gearing down for a red light, just befote the car is stopped and under no load at all, it will let a big puff of smoke out. Im baffled by this since the car is running great.
Sometimes it doesnt do it at all, other times its every red light i stop at.
I've even had a friend follow to tell me if he smells oil and there was no odor. I did notice small amounts of oil in my turbo piping... Is there any way this can end up running thru my engine?
