I saw something about this on another forum but it wasn't Alero specific - having problems with the RPMs shooting up and down when driving, most commonly around 60 and 90-100 km/h


i'm in need of a new fuel filter and basic system cleaning but i'm wondering if this is a symptom of a bigger problem?

Change the filter first-it's cheap, easy, and you need it anyway. If the problem continues, we'll go from there. It might fix it.
