Ran up to Harrisburg PA from Northern VA, USA with my wife.
250 mi RT.

Velvet.

It is occassionally stalling at lights. MAF a good suspect?

And I can't believe I forgot to deal with this:

I changed the wheels from 18" to 17" (snows).

I only noticed the speedo discrepancy when I was finally able to power a GPS.
The speedo is fast by about 5-6 MPH. Which will be throwing off the OC,
ODO, etc etc.

Is there a user reset? Or must it be done by a tech?
Is it electronic, IE a menu selection, or is there a little gear set that
has to be installed somewhere?

Gracias!
