2010 XC90 3.2 Engine Chugging
 

Hi,
Just joined and have a question... We have a 2010 3.2 with just over 103000Kms... Engine started "chugging" this morning while on the highway about 40 minutes into my drive. Never had this issue before. No lights on dash just an odd hesitation/chugging (best I can describe) at speed. Once slowed down it seemed to get better.

Anyone have something similar like this ever?

Thanks

FYI... Fuel Filter. Replaced it... good as new.
