I get the same thing on my 95, but it only does it for a few minutes after startup and only at or near idle. Not the getting stuck at any RPM part, just the needle reading 0 RPM until the engine (22RE) starts turning at about 1500+ or it warms up a bit. I used to think it was related to my stereo (too much draw on the alt.) but I've noticed that with the cooler weather it doesn't matter whether the stereo is on or not.
