we basically just sealed from the MAF to right before the engine.........hooked up an air compressor and listened and felt for air......

Log these data blocks:
032 - Long-Term fuel trim at idle and under throttle. The first two values should be within -10 and +10 and relatively close to each other. If the first is negative and the second is +18 or higher, MAF meter is probably bad (Mine were -.5 & +18.4 before replacing MAF meter, and -0 & +1.4 after replacing).
211 - Provides actual and calculated expected MAF values. Log this datablock while driving and see how the values match up.

A leak probably wouldn't cause you to go lean though. In fact, it'd have the opposite effect. You're getting too much air.<ul><li><a href="https://forums.audiworld.com/a4/msgs/1659806.phtml">Click here</a></li></ul>
