so i just got a 92 civic 4 door auto... the speedo did not work so i replaced the speed sensor. So now the speedo works when it wants sometimes says i am doing 80 sometimes 20 or just dead. Is there some problem i am overlooking?

I am having teh same problem with my 99 SI. It's rare but it jumps around and sometimes goes all the way to 100 when im only doing 40 then slowly goes back to 40 then dies and so on. Not sure what it is but I would like to know what to look for also.

yea same thing here. i was doing 40ish then it went 20 then 85 held there for a bit then back to normal. Yesterday though i drive all day and it was fine

Could be a bad gauge cluster, bad vss, or wiring from the vss.
