Just installed my wideband O2 sensor. At idle in closed loop after a 5 min warmup its reading 17-20:1 Lambse values are at 11.7-12.0:1, the O2 volts are really low (0.03 sometimes stuck at 0.003) and the car stinks. I'm assuming that maybe the O2's and wideband are too far downstream with my Long tubes, but if they're cold shouldn't they be reading rich not lean? The wideband sensor is in the x-pipe directly after the collector. I'd love to drive it but I've got the car up on jack stands and have a few more things to do. When I rev the car up to 2000rpm (still in CL) the AF goes to ~15.5:1 and lambse reads ~13:1 wich seems about right so I'm assuming once I get the car good and hot driving along it should be accurate. If my A/F and lambse values are off at idle, do I just tune this thing by smell? Also, I don't have the noise filter capacitator in yet between the ground and wideband wire since I don't have a solderer, but that shouldn't effect the overall accuarcy of the reading.
