View Full Version : Having trouble with my Wideband NGK AFX

04-11-2008, 12:10 AM
Well, after getting the car running I hooked up the wideband, and it was wroking perfectly fine. Everything was stock, except bolt ons (intake,fmic,exhaust,bov,pulleys, etc..)The a/f was reading a constant 10:8. But now for some reason before it hits 11 a/f it shoots up past 16:. I read the instructions recalibrated about 6 times. Even did it with a shop, but still does the same thing. I only had the wideband in the car for about one week. Each time I take out the sensor it looks perfectly fine with no excessive carbon or anything like that. The Sensor warms up fine. Just weird how it was working perfect a week ago and then it does this. Anyone using a NGK AFX have any trouble. Forgot to mention I even restarted the whole unit by unplugging the power to it. And though I bought it about 4 months ago Ngk wont help me out, I had talked to there technical support but they didn't really help, and the warranty is only good for 2 months. With out my wideband I wont be able to install my 565cc injector http://images.nicoclub.com/forums/images/smilies/frown.gif . So if anyone can help me in assisting on what to look for. I mean if it was working perfectly one week ago, and I never touched it, why would it do this now. Thanks for your help
