Hey I have been doing some searches on various issues and it seems that we all have our little issues. Some are similar and some are not. I decided to start a new thread only because I am posting a link to the video I shot of my Audi starting. It is a 1.8T (97).

Please help if you have any idea of what is going on. Thanks.

Looks like a possible vacuum leak. Try searching surging or pulsing idle.

I would say defiately a vacuum leak or your dv is leaking causing the surge right after you let off the gas.

Oh yeah this is aside of the bouncing idle. My car starts almost all of the time, but now twice in two days I go to start my car and there is nothing there. It just won't fire up, I turn the key and it sounds like everything is fin but it just won't fire up.

The video image never flipped back, I just used the iSight on my MacBook using iMovie.

Cranks though right? Just wont turn over?

Pressure test the system to check for leaks to start I would say

yeah vacuum leak would cause that but check your idle air control valve, which could cause idle issue

Not to state the obvious, but did you attempt a throttle body adaption?

Check the PCV (breather) hoses and connections. My breather pipe was brittle and was cracked wide open, causing a noticeable "pulsing" at idle. Definitely sounds like a vacuum leak somewhere.

Good Luck.
