    My Volvo S80 T6 1999 is hunting when in neutral, I have tried the Mass Air Flow Meter but this did not work, cleaned the throttle body, has anyone other ideas?

    After reading all the various threads on the throttle body I cleaned mine. The issue that prompted my cleaning was that the throttle response when cold was very erratic and non-linear. Once it warmed up it was fine. The cleaning cured that issue. What it didn’t cure was a slight surge at 2,000RPM/60MPH. I thought the two might be related, but evidently they aren’t. Any more suggestions on the surging issue?

    to: Jon Cotterman: got the same surge issue as you even after cleaning etm. wish I could help you, but short of getting volvo to replace badly designed etm, don’t have any practical advice.so far, volvo has refused
    to replace etm on anything after 2002 model year, so my 2003 doesn’t qualify even though it was built in oct.
