<img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/confused.gif" border="0" valign="absmiddle" alt='???'> I just cleared my ECU code, but before I did, I received the code 81 which is "Vacuum cut bypass valve". *What the heck does that mean? *
A couple of days ago prior to getting this code, I was showing off and revved my engine pretty high and burned out next to a couple of Hondas, which I only reserve for special occasions (hardly ever, 2nd time burning out since owning car). *I have an Injen CAI and Apex-i N1 catback if that means anything. *I was thinking I have some kind of leak on one of my hoses, but am really not sure. *It doesn't sound like a big problem, but please enlighten me if it is. *It's a '98 240 with only 39K on it.
