"shock related loss of power"


Aug 2, 2001
Hello All:
199.5 TDI Golf, auto ,99889 miles
As the title suggests I am having a loss of power after hitting pot holes or wash boards in the road. (roads in northwest Illinois are very bad).
At times the problem will correct it self,but other times a key cycle is necessary.
There is also a street that I travel which has a long uphill grade after a stop. I give it throttle,the acceleration starts but then fails,backing off on the accelerator at times restores the power back to normal.(this street is also rather rough)
I have replaced all the vacuum lines. Could the N75 be shock sensitive??

Also were can one buy this valve on line??
