I did have the mechanic reset the system. No lights have come on yet. Although I am waiting. Can I ask my mechanic to replace the vaccum lines and clean the MAF. Would that be a good place to start? And is this something that should eventually be done anyhow? I believe at 102k mi. I am due for a new fuel filter. Will that make any difference? Neither mechanic has mentioned that. I just read that in my manual. Why wouldn't they do this in the first place? I am working with two indy volvo mechanics here. All they work on is Volvos. I am a stay at home mom and I have to say I feel like an ass making such requests because I don't know a thing about cars. And they know it. I wouldn't mind at all getting my hands dirty and learning to do things for myself. Thanks for the input all.
