I installed my air/fuel gauge yesterday and everything worked perfectly but after a while of driving it was running waaay too rich and it felt like a 10-20% decrease in HP at WOT. I'm thinking that maybe by installing the gauge and tapping the oxygen sensor messed something up but I'm not sure. Anyone know what could be wrong?

you usually need to hook the Air/Fuel Gauge to a Auxuillary 0/2 Seonsor. I mean you need to buy another 0/2 sensor and install it somwhere after the headers.

You shouldn't run the gauge off the stock 0/2 sensor because its too much of a load for it to handle. so it gets false readings.

Un-hook it before you do permanant damage and get yourself anothe 0/2 sensor and install it yourself.
