Mine is occurring around 2900-3200rpm (normal cruising rpm) But when i'm on the accelerator the symptom goes away. Prior to upgrading my bypass valve, the issue occurred at a higher rpm range 3500-4000rpm. The theory is that it is air turbulence on the MAF's and/or poorly designed reciruclation tube where it connects back into the main tube going into the blower. The recirculation tube right now basically T-bones into the main tube when ideally it should curve into it facing the blower.

But as of now, i have no solution. The shop i take my car to wants to extend the pipes before the MAF's to see if that would help. So if you find a solution, please let me know.


you can build a air box that should fix the problem. I took some thin aluminum from lowes and bend it around the front crash bar under the filters and up around the back of it. I did this and do not have any problems at all. this will prevent direct air from entering the filters and causing the MAF's from getting a bad reading.

kellyefields,
What led you to make this airbox? Were you having the same drivability problems as we are describing here?

Can you provide photos of the solution you came up with?
Thanks.

also, i know there's a shroud that comes with the kit already that blocks air flow. But i'm assuming yours is larger and placed differently? And as irondoc stated, did you also experience these symptoms?
