I was having mysterious engine problems. Some days the car would drive fine, most days you could barely drive the thing. If I pressed the gas pedal more then 1/4 way down it would lose all power and then buck like crazy. I followed the LJet manual on Gregs site and had done pretty much everything, short of pulling the injectors. One time when the engine was idleing really rough i poped the hood and started squeezing the vacum hoses with my fingers and blipping the throttle to see if i could feel anything. I noticed that when i pinched the hose going from the Auxilary air device to the manifold things seemed to get better. I pulled the AAV and put my finger over the one end and blew in the other and sure enough it was coming out the seal. I didn't have a picture of my own so i'm borrowing the one from Gregs site. The seal on the opposite side of where the screw driver is pointing. I've just blocked off the 2 hoses while i fix the AAV but now the car is driving fantastic.
