Wow, those are a lot of good calls. Thanks for the sugestions.
What I've done: The CEL popped up, which prompted me to cleaned my K&N filter. First time I've really done it, so it's possible I over oiled it, i'll check the maf. In addition, the fuel pump was replaced right before I bought it (about 800 miles/1 month ago), so i doubt it's that (but it very well could be!). if it IS plugs and wire...well DAMN, time for an upgrade!

Thanks again!
