P0101 code is driving me crazy!!!!!!!!!
Ok as we all know the P0101 code can be many things so I will try to make this short and simple. To fix this problem I have done the following :
1)replace Throttle Position Sensor
2)replace K&N with paper filter
3)clean MAF and inside of Throttle Body with Q-Tip and rubbing alcohol
As usual with iritating problems non of these items above curred the problem
Before I go the more expensive route replacing the MAF(Jim Pace 85mm descreened LS1 calibrated) or the Throttle Body which I ported myself. Is there anything else I havent done that may cure this code being thrown ? I'm as lost as a Billy Goat in trying to remedy this problem HELP........
Also being I have a stalled A4 when this light is on performance is drastically reduced

actualy the last thing was mti retunning a new pcm, old one was fried after getting it back via mail from AMS. The SES light has been on ever since with the P0101 code..aprox 3 weeks now very poor performance also

There is actually a P0101 allowabled error table in LS1 edit that can cause this code to be thrown erroneously. If you are supercharged, you have to adjust this table up to avoid getting this error (on some setups). However, being NA you shouldn't have a problem (unless they messed with the table).
First, I would ask MTI if they play with this table. If they have a sharp tuner there is some hybrid MAFless tuning that you can use this table for with the larger cams and perhaps MTI is trying this and just forgot to turn off the SES light for the code.......minor mistake.
Additionally, if you have a crummy port job on your MAF with a very large cam it can throw this code.
If they don't mess with the table, then there is one thing you might want to try.....
Having you car sitting there at idle unplug the MAF:
If the MAF is still being used then the car should stumble and the idle should drop. With that being said then most likley your P0101 is a spike/connection problem. I would start checking grounds and wheather plugs for obvious signs of damage or loose connection. Additionally, I would check your PCM plug for any folded over points.
If the MAF is dead then the cars operating won't change when you unplug it. If the MAF signal is dead, then most likley it is a disconnected wire, blown engine fuse, or boofed MAF.
Good Luck

Kevin, I throw this code ever so often, lots when I spray. How much would you suggest raising the allowed value for a starting point? Something like 10% or 20% across the entire table?

Try aiming your nitrous a different direction. Directly blowing onto the MAF is a certian way to freeze the thermistors and a guaranteed way to run WAAAAY rich. Try shooting the opposite direction or put the nozzle around a corner.
If you are just running such a big dry shot (~175+) that the MAF freezes no matter what, then you may as well disable this code in the upper flows. For all higher flows I would just input the max value.
Good Luck
