I've just had this problem develop. When I'm coasting with my foot off the throttle, and I then give my car gas it goes lean (16.0 - 17.0) before my WB02 reads stoich or goes rich if i give it alot of gas. It goes lean enough that i notice a hesitation. It only lasts for a second or two. I thought maybe my FPR was on its way out. The only reason i mention that is because when the problem started i added a little bit of fuel pressure and the problem went away. Now I haven't touched it and the problem is back. My FPR is one of the old school SX regulators.
I don't have anyway to watch the FP from inside the car. I started a thread the other day about having lean idle and now I noticed that my WB is sometimes all over the place at idle. Sometimes rich, sometimes lean, sometimes stoich.
