Wideband Issues
Alright, Im going to give as much info as possible.
I have a 2003 Evo, stock tune.
The car is slightly modded, (Intake, TBE, intercooler with LICP.)
It has a PLX m300. When Installing the exhaust, I ended up cutting the wires, and reconnecting them.
The wideband worked fine for months. Today it rained pretty hard. I drove home, and my wideband was reading fine. When I started my car again, the plx was reading "LEAN" and eventually started reading normal, then a few moments later, back to "LEAN" Now its consistently reading lean.
I dont know If my wideband is messed up, or my car is ****ed!

im pretty sure I taped it up good. I used wire crimp on connector and wrapped each individual with electrical tape, but I could image water still got inside.
Why did you cut the wires just to install an exhaust? When you reconnected them it should of been either soldered with heat-shrink or the crimp'n'seal butt connectors that make the connection waterproof. Otherwise this is just going to keep happening. Sounds like you ruined the sensor when water got into your connections.
its probably the sensor. I would also check to make sure all the wires where you had cut them are still together. if one isnt connected together well it will either read rich or lean on most widebands.

Test the sensor and see if it is going bad.
Different brand, but results should be the same:

i have the same issue now.. last week after a nice snowfall in chicago i went out drifting.. after that the next day i noticed the wideband would read lean non stop.. i checked for an exhaust leak and nothing but my plug where you hook up he sensor to the cable is right on the buttom where the exhaust is. would water getting in there damage the sensor since its open to water or snow?
