Your Vehicle Speed Sensor is not connected properly. Pull it off and blow in it and then reconnect it.

I bet it acts like a Tach sometimes

well that same thing happened to me and it just happened one of the wires was a bit loose from the speed sensor so i just tighttened that up and it started working fine.

frostcivic

where would that be located?

BlownVR

mine was located at the very back right of the engine bay where alot of wires are. it was a blue wire but your probably notice if it disconnected.

VSS plug is close to where you would full your transmission fluid.

Most people take the VSS off to fill the tranny

hey, time to bring back a dead topic

my speedo was working fine... then, i swap distributors and now it's bouncing like crazy.
my friend's speedo did this before his dist went out. coincidence??

CHECK YOUR DIZZY 90% CHANCE IT'S YOUR DIZZY MAYBE ITS GOING OUT USUALLY IT'S NOT YOUR SPEED SENSOR IF IT'S NOT PLUGED PROPERLY YOUR SPEEDO WON'T EVEN WORK. BUT I'M PRETTY POSSITIVE IT'S YOUR DIZZY MAYBE THE COIL.

that's what i was thinking.. my speedo USED to just stop reading.. go to 0 and stay there.. i took apart the VSS and solved the problem. the electrical connector was dirty, where it connected to the harness. now it won't go below my set speed. ex: if i'm doing 40mph, it will bounch between 40 and 80-100mph. weird. ONLY did this after putting on the different dist. OH! and i get a CEL now, but with no code. WTF??
