rebuilt new motor, and i installed this new NTK 02 sensor at the same time http://www.summitracing.com/parts/NGK-21002/ its been 4 months and roughly not even 3000miles and the sensor just stops working?

i have my car outfitted with a LC-1 wideband as well as the stock narrow band 02 but i have the stock narrow band hooked up to a NB stewart warner gauge which is also new. drive it this morning and all of a sudden im reading 17-17.9:1 on the wideband and the car feels sluggish, i look at the NB gauge and the LEDs arent jumping around anymore, kinda just 1-2LEDS are lite and when i step on the gas the LEDs stand still, once i let off the gas the LEDs kinda barely jump alittle but only on decel.

im pretty sure its the sensor that went bad, wires arent melted (headman LTs) so without the 02 working properly im basically runnin in open loop, sensor also gets hot enough so it should have been working... but nothing.

 

did a datalog and the NB 02 sensor isnt doing squat... never goes into closed loop. mv values are constante 450-500mv which is freaking out my BLMs etc. so this confirms that its the 02 sensor that has taken a poop!

so i give the NTK 02 sensors a big THUMBS DOWN!

anyone have any other brands of 02 that work well? ive used standard motor products and they are ok, i have a bosch12014 in front of me and im gona try that tmrw, seems like a better sensor tho.
