Engine Combustion Problem? S70 1998

Hi All,

First of all, thank you for helping me out. Here is the problem I am having with my S70. Sometimes the engine chocks (2-3 seconds) and feels like it is going to stall. It is like there is not enough air or fuel in the combustion chambers. However, the rpm meter doesn't really drop. Maybe it is doesn't react fast enough to the sudden rpm drop (feels like there is an rpm drop by the way how the cars shakes a little). Does anyone know what is wrong with it? Maybe the spark plug or something? Please help.

Thank you,

V4L
