I saw this on another site and wanted to see if anyone had tried it and what their opinions were. http://au.geocities.com/ozbrick850/engine-o2-quickfix.html
I'm trying to track down a cause for my Mileage/performance loss over the past few months. I thought this couldn't hurt. But I don't want to damage my O2 sensors because they will cost $300 to replace both.
Anyone tried this before? any feedback?
