Target: $5.99 for the engine cleaner in the ato department. I think it is called CD2 or something similar. Search for clean engine in the asthetics forum and you'll find a few threads about it, but the pictures of the box that I remember are no longer posted. I tried it myself last fall and it works great. I also used Simnple green, but it was too cold to have a hose hooked up so it didn't turn out as well as the CD2.
