1G help with lean running

[alexs' tsi]

i have ecmlink v3 and took a log for you guys to look at, basically the car leans out hard, like 18/1, (using lc1) the plugs look lean and the car runs like shit too when the wideband reads lean,
sooo a background,,,
one morning the car ran a little lean on cold startup but went to normal after i started driving, but i did notice that any sudden throttle pos changes made the car lean a little hitting 16:1 just long enough for you to see then going back to normal afr at the new throttle position, now i cant barely get it to run by itself, runs way to lean to let it idle and revving it still reads lean, like 17;1-18;1, the car is definetly leaning as i have no exhaust leaks before the wideband so it is accurate, any help please i am stumped ??

looks like a BLT is in order, some hose fell off somewhere or you have a rupture in a hose, crack in the piping, something to that effect. I think your exhaust is fine, but there's an opening for air to get in somewhere along the intake tract.
