Default P0101 after head swap
Threw that code after the head swap...couple Ideas on what could be wrong
Let me know if this sounds like the problem

Leak on the intake manifold, causing the MAP and MAF to act funny, throwing the code

Or maybe the car needs the MAF tuned, recalibrated.


Car is 04 GTO A4, w/ 224R and 243's w/thinner gasket.

thanks in advance.

Let me know if there is something else it could be.

and Maximum Delta values were increased to see if that would fix the problem...still throws the code....Also cleaned the MAF and tried a different MAF and still the same code.

gonna check the intake gaskets tomorrow and see, please post if there is anything else I can check...until then I guess I'm stuck on the SD tune.

Do you have a scanner to monitor MAF activity? Check the Eng Sens fuse if there is no activity.

we multiplied the numbers by 4 or so, can't recall off the top of my head, and I'm not at my friends house where the software is.

like you had mentioned in another thread of mine.



I'm thinking there might be a vacuum leak somewhere...what happens is that
the idle in drive is ok...but idle in park starts high but eventually comes down to normal.
