I noticed today driving that my AEM UEGO was no longer working. I'm still getting a display, but it was just stuck at 14.9. It would not fluctuate with the speed of the car or anything. Turned it off and started the car back up ... same thing. I'm not exactly sure when it stopped working, might have been recently or a while ago. Car still runs fine ... but hmm. My initial thoughts are a wire came loose (maybe a ground) somewhere, or the actual O2 sensor in my downpipe went bad. I'm planning to take a look at it tomorrow but I thought I'd post here and see if anyone had this happen to them tomorrow. I may even call AEM and see what they say.

I've been tossing around the idea of purchasing a wideband. I know, I know...I've been in the game long enough to have bought one of these already. But my primary concern was getting the car "stable", using my cash for that at first. Now I think I'm to the point where I need to know whats going on when stumbling and poor idling etc. occurs. I've been searching around for the last 3 hours or so trying to decide which system to go with. I'm not worried about modding, and MAF translators and all of that stuff any time soon at all. Just a quality, nice looking easy to understand system that I can get a handle on AFR for troubleshooting. Innovate AEM PLX Prosport EVO Any Input would be great guys. I've searched through the threads, but didn't really find what I was looking for Thanks -N8
