Yesterday I feel a big loss of power... specially when I up the gas...
I checked the MAF, then the EGR, the N75 valve... but nothing...
But the lucky come to me... While I'm checking the little tubes from the depressure control to N75 valve... I seen a big scratch from hot..
Bingooooooo!!! i replaced the tube and the power go up!
This is a mine experience with power loss with a pd engine...
Sorry for my bad english...
