car stutters when you give it gas,especially in overdrive. V70-XC70 1998

Hi all,
I'm really hoping this isn't serious but car hesitate on highway usually at its worst when there is an incline.It runs fine at around 50-55 but starts to stutter and shake at around 2500rpm.Any ideas? Thank You

Could be any of 1000 things - marginal ignition, minor intake air leak, dirty throttle body, partly clogged injectors, low fuel pressure, etc.

If the symptom isn't severe and you're not really up to date on routine maintenance it might be simplest to just go through each system and make sure it is tiptop. You might have several minor things conspiring.

If all your care is really up to date and this happened suddenly, then you have some diagnostic work to do. The old rule would be start with ignition, then primary electrical, then fuel system.
