Throttle Body Problem?

Recently, my 1999 S70 with 82000 miles has begun to run rough when transitioning to low rpms, for instance when coming to a stop for a traffic light. It almost feels as though it will stall out, but hasn't yet. Then the problem corrects itself after a second or two. Could this be the start of the dreaded Electric throttle body problem? So far no waring light in this regard.

Thanks for any input.

    Throttle Body Problem?

    posted by  someone claiming to be ksg on  Mon Jun 27 02:51 CST 2005 [RELATED]

    Sometimes happens on non-electronic throttle bodies and idle air motors - due to built up dirt - without there being a problem with bad parts. Would it be easy to clean the non-electronic parts of air intake/throttle body path?

    Another possibility (assuming you have an automatic trans) is the torque converter was in lockup and slow to release. Does it happen if you start then stop before reaching the upper gears?

      There doesn't seem to be a pattern with respect to engagement of upper or lower gears. I certainly do not think it would be a bad idea to clean the air intake. I wonder if it could be on the fuel delivery side? Perhaps while I am at it I could change the fuel filter and add a bottle of Tekron to the gas.
