No reason... just the $$$

 

Agree that problem is likely on non-pressure intake side. I had idle problem without codes before mile. I had a driver's side turbo inlet hose loose and there was a leak between my airbox and MAF pipe. Once these were sealed she idled like a champ.

 

Thanks guys. Sounds like I should check the easy and obvious before I go digging...

 

ive had that same sound your inquiring about its not always there only comes on for me when i have bad gas in the car shrug

 

I don't have it all the time either, but most of the time...and always at the same RPM.

 

agreed i had it 4 times one day and the only thing i did different (in the middle of a 2500mile road trip) is i gassed up with ****e 90 octane from a crappy really really little town and i drove the car until it was basically outa gas no boost filled up with 93 shell gas from a high traffic station and it hasnt been back but i also need a set of new plugs n coils but its the exact sound u have explained. when did u change yours last?

 

When I first heard the sound, I datalogged, found nothing. Changed plugs(was due anyway), coils, tried new MAF too, (have since put old one back in). I have always run stock airbox and paper filter and have 100% met injection only running between 1.3-1.4 bar. Was gonna do O2's, but couldn't find a reason to, as it runs good and the datalog don't show anything out sorts.

 

Uh oh!!
Just let me know when, it's ready for you!
Hopefully it is something non-crucial!

 

Need to do a full on hose check. Call you tomorrow sometime...

 

Sounds good!
