I've noticed a slight lag or bogging from time to time in mine but it's never been bad enough or last long enough to bother really troubleshooting though I would suspect it could be a combination of the old fuel injectors and 200k mile coil packs. I don't know how well or not your car runs but I'm almost 100% positive I have a small hiccup in my head gasket somewhere that I'm going to get fixed later this year that could potentially cause the initial loss of power/bogging down like experience too. It runs pretty rough but I do have an exhaust leak/issue as well that could contribute to that.

I would have considered the MAF as well if the problem kept up. How long as it been happening?
