O2 Sensors
I have a 98 Ltd with 130k on it, i have recently been getting a constant downgrade in fuel mileage, i have also heard that the o2 sensors on 4runners start to fail around now, would those be a big factor in losing the mileage? how much are they to fix?

Be sure to only use NGK (actually, box will say NTK) or Denso. Do NOT use Bosch (they're a fine product, they just don't work well in our trucks).
You can have a bad O2 and it not throw a CEL. As they degrade, they will err towards running rich and your fuel economy will suffer.
I just replaced mine, it was about $85 from Summit Racing.
