This is the first non-gear related speedo issue I've had with the 92. Mom borrowed it last week while (coincidentally) I fixed her speedometer. Now, I can hit about 45mph in neutral with a blip of the throttle. I'll be able to hit 20mpg now, but I'd still like to know where to start. VSS? What side of the wiring should I look at? Is this a sign of a bad PCM? I'd think the problem is in the wiring, possibly grounding out on something.
