I've searched and read all the posts to no avail and I have this same problem--except in my case I'm losing power

Everything I read makes mention of the filter being clogged, but my problem doesn't seem to depend on the level of fuel in the tank. If its carbon build up, how can I clean this off?

I have almost 108,000 miles on my 98 Mystique LS

Thanks
