In the past few days I have been letting my engine run hotter than normal (over 100C). Initially, I noticed this really strong chemical smell, and black smoke on hard acceleration.

After a day or two, the smell and smoke are gone. The car did idle a bit rough after doing this, but that is smoothing out. I would like to run it flat-out at 100+ mph for a while to really clean it out.

Jet -- I never heard of PowerFoam, but have used Z-Max with great success up until about a year ago, when I could no longer find it at my local stores.
