Hi, I recently had these codes come up, where should start?

My 2000 A6t 2.7 is currently down on power and surges and or bucks when I step on the gas at speed. I think I can hear a vacum leak some where, but I can't seem to find it, nor do I know where to start looking. Engine idles at about 800 rpm's. Help!!!!!

MAF

Torque Convertor Pressure Control Valve

Control Valve N218

Vacum Hoses

Piping for Secondary Air Injection Valve

Any help will be appreciated.

Thanks

Secondary air pump issues - it seems that it's a vacuum line issues. Audis use goofy braided rubber hoses for that stuff and they fall apart like no other - just follow the lines and see if you see any tears, rips or disconnects.

it's a PITA to remove (with the factory clips) and replace.
