Hi bigdaddyoyo,

We can't recommend that book for your vehicle, since the '99 was most likely different enough that it couldn't be included. Bank one refers to the cylinder bank on the right (passenger's) side of the vehicle. Sensor 1 is the O2 sensor before (upstream of) the catalytic converter, and sensor 2 is the one after (downstream of) the converter.
