I posted this on a Volvo forum yesterday with no luck. Perhaps this issue isn't limited to just Volvo?
So far, it's done it once on Monday. It wouldn't go over 1500 RPM in a parking lot, but then went to about 3500 RPM and finally shifted. No check engine lights and the engine sounded fine. It was completely issue free today (8-23-17).
I replaced the throttle body with a Bosch unit back in March. Perhaps the MAF sensor is going out?
One person did chime in saying to check for codes with a scanner; there aren't any.
Thanks folks.
