[s-cars] '95 S6: Surging and a Jerking under Acceleration

[HOOG23 at aol.com]

Car has 71K miles.

Just started yesterday - very intermittent while accelerating (under partial 
and full throttle).  The rest of the time the car is fine.

>From prior posts I guess I should I look for boost leak.

Are there any common items to check?

Thanks,
Dave
