think my wideband is f*cked up VIDEO
I have had a plx m-200 wideband for 6 months now. I have been using a volt meter to watch air/fuel ratio's (not easy to do). I finally broke down and bought a gauge. When the wideband is first turned on the air/fuel is at about 14.7 for the first 30 sec.(warming up) then it starts dropping down to 19. It stays at 19 for about 5sec and then the afr's just start jumping around anywhere from 19 to 14 and can't read it because its moving so fast. All this is with the engine not running. I drove the car around just to see what would happen and the afrs are still all over the place. I then hooked up a volt meter and the volts are steady so im stumped.
here's a video, the car is not running http://i1.zvhost.com/1/g/gpab2xvd.jpg |

Re: wideband jumps around VIDEO
only run a wideband direct to the battery for most accurate readings, but if the voltage reads steady, id say somethings fucked up.

This morning I went out to move my car, and the gauge worked for about 30 seconds and then just started flashing radom ---- again. It showed about 15:1 at idle. Its almost like it works until the sensor gets hot.

The sensor could also be dying. With my lm-1, when my bosch sensors go... i get random jumping of AFR readouts.
