Rough Idle -- VAGCOM results inside

[Kyle H]

The car isn't throwing any codes, I scanned block 003, 032 and I have no idea what these readings mean. Any ideas?

[Poopie]

no idea what you are trying to do.

[Kyle H]

Whoops, I'm sitting in this guys car right now trying to figure it out.


Basically in when you let the car idle the rpms fluctuate from ~800rpms to ~1300rpms and bounce up and down like that.

He posted a thread before and somebody said it could be the MAF or TPS, so I scanned block 003 for the TPS measure and 032 because this thread said it shows important stuff.

HALP!

[Poopie]

my initial guess is a bad maf.

[Kyle H]

Well somebody one AF got it (crazy, huh?) we just needed to align the throttle body... we went into block 060 and realigned it, and it's all good to go.

Thanks for reading.
