Weird problem with A/F meter
OK here goes. I just got back from a 500 mile round trip and noticed that my air/fuel meter seems to be stuck at stoich even during WOT. It kinda wanders a couple of bars in either direction but it never leaves the Stoich band. It used to wander rapidly from rich to lean under normal driving conditions and go to rich under WOT but now it stays at stoich. Could my O2 sensor be going bad? I just changed it about 2 months ago and had only about 1500 miles on it. My SES light has not come on yet. Any suggestions? Thanks.

It sounds like it went bad or is bad. Did you use any sealer that is harmful to it when you installed it?
