First off, its actually a very good thread title, thread titles are supposed to give you some idea of what the thread is about, not help, or this sucks or, (insert other vauge title thread here). That way people don't waste time going in and seeing its something they know nothing about.

I don't think bad wires would completely cause your car to shut off, just to run badly. I think you need to go back and check for a vacuum leak because if its not your MAF or IAC this really sounds like a vacuum leak. However, cleaning your maf might not do much if its shot, you have any friends with the stock MAF? Throw theirs on real quick and see if it runs better, it takes 10 minutes to swap out, atleast on my car, i can't imagine it'd be much different on yours, also did you do the plugs recently? If so did you gap them correctly?.052ish if i recall correctly. Im betting on MAF or a small vacuum leak you may have overlooked.

I would put my money on a vacuum leak too after watching the vid. Also, what is up with your speedo not working?
