I added the BG 44K to my full tank, drove it hard for about 40 miles and bingo! the rough idle was gone. I started to notice some improvement after about 20 miles with only random miss at idle. The idle was smooth after about 40 miles. This stuff is amazing...it works! I will observe for the next few days to see if it holds up...

Reinhard Kreutzer, thanks for the tip.
