well i got it hooked up, but a couple of questions:

1. is it supposed to stay on while the car is off? it constantly shows the last lean light when the key is out and makes noises and i can hear clicking in the engine bay, probably coming from the O2 sensor.

2. when i'm at WOT it shows so lean that no lights show up, shouldn't it read rich?

3. vandy, i think i remember your battery and brake lights would come on sometimes. well mine did that and the car died after i had it at WOT. was it your alternator?

TIA
