ECUflash says P0103 is "MAF Sensor High Input". A 70-80mm maf tube should work well.

I got the same code today and it's definitly P0103. I'm running just stage 2 reflash though. A snap on scanner says the problem cause is:

1- A big vacuum leak
2- A damaged air duct hose
3- A mechanical Problem
and 4- Broken MAF

I can't find any vacuum leaks and I don't have a way to test my maf. Any ideas where to start instead of buying a new maf ??

Get a tatrix cable and log it. Then you can also reflash with open source if needed.

Tell me how strange this is. I changrd my oil because it was about time for one, and it took away the code! This just blew my mind that i fixed a maf code by changing my oil.
