OK, so for awhile now my car has been throwing this code and i keep erasing it. so i finally broke down and bought vagcom. Im not sure where to log for this so if someone could help me out that would be great. it keeps throwing

I understand what it is. but im not sure how or why. i have an afr and it never goes rich.

it only seems it throws the code after a long drive and i push the car a little bit. the dealer read the code once and just erased it cause they "could not duplicate". I especially get this if i push the car so hard that it goes into limp mode, its not permanent limp mode. if im racing on the highway or hold 80+ for too long when i get off the highway the engine will only boost 5 psi but in about 10 mins of driving or sitting to cool down the problem goes away and it is back to normal.

could it be that with all the modifications and hot ambient temperatures of florida i simply am so heat soaked that the air just doesnt match the fuel demand?

the code is also thrown about every 500 miles which makes it more interesting of why it takes so long to throw.

if anyone can help or has any good suggestions please help! thanks a bunch!!!
