M-300 wideband sensor replacement
 

After this winter storage my M-300 wideband is acting up. It reads 12,13,14,15, 18 then air and LEAN after startup and during driving. I checked their website and a replacement sensor is $79. Does anyone have an alternative for this sensor or may know what my problem is ?

thanks, Tom

Is it in the stock location? It might be shot... I've heard that wb 02 sensors don't do so well in the stock 02 sensor bung.

It is a little lower on the DP than stock. anyone else have any input ?

The sensors only last so long. Have you called PLX yet? You should be talking to them before trying here....
