bouncing speedo
 
Hey,
When I am driving often my speedo starts bouncing up and down by about 10 kph, while I am keeping a constant speed. Does anyone know a fix for this?

Start carrying a spare ignitor and a 90 degree allen head to replace the trailing ignitor when it goes....you'll feel a loss of power and the tach will go completely dead when the ignitor finally dies...:cool:

Since when does the speedo run off the ignitor? :p:

Not sure if you can fix it. Mine started doing that as well so I just replaced it.

If your speedometer cable is sticking, your speedo might bounce a little.

Not only since when does the speedo run off the ignitor, but since when is it held in with allen screws? :p:

Mine is just about dead, it works when it wants to.

It's just the cable. Try some graphite, it may help.

851stgen12a 02-27-03 08:24 AM

check to make sure the cable is pluged into the tranny good.... it might be loose...

pillage6 02-27-03 10:11 AM

That's what I am thinking, but it is raining here and I don't wanna get under the car right now.

Make sure the cable doesn't have any sharp angles to negotiate too. Could be binding on a tight curve to the speedo.

pillage6 02-27-03 10:48 AM

Is there a problem spot you have in mind?

85RX7GS 02-27-03 11:09 AM

The cable is a piece-o-cake to pull out at the transmission, it's the other end that's kind of tricky.

So, how long have you been on the new medication...? :p: :rofl:

I have learned many cuss words when watching people work on in-dash things.

If you get lucky you can disconnect it from the tranny and pull just the inside out and replace it. Maybe it didnt break yet or it is broke close to the tranny.

TaoTeStephen 02-27-03 05:03 PM

I have the same problem -it's the cable coming loose out of the back of the guage. You *can* reach up there and tighten it up but it takes some doing and knowledge of what the thing looks like.

I will take a look at the tranny side first, then venture into the dashboard if that doesn't solve the problem.

sigh....could you tell it was late at night for me....slept in at work (SBC) when we got iced in (YES, in TX....) and was posting despite being tired and delirious.....:p:

so...what's it look like?

I have no radio, just a space for it, and a bunch of cut wires. So, I pulled out the loose wires to see how many there are, etc.

In doing so, I managed to mess up my clock. Now it's dim unless the headlights are on, and always resets to 1 o'clock when the car is turned off.

Today I noticed my speedometer doing exactly this- it's bouncing, fluctuating as it rises and falls. I was afraid something mechanically might be going bad. Being that the tach already doesn't work, it's not helping that my speedometer might stop too.

EDIT: Oh crap sorry. But my car IS doing this...not like it's a new problem I'm sure (:

don't worry, just follow traffic in front of you, and if there is none, go slow and wait till you get passed :) heheh

YapaKanichi 05-10-04 07:19 PM

please man when i had my Honda, the speedo didn't work for the first year I owned it lol. Just drive with traffic. the slower traffic that is, just to be safe.

Illswyn 05-10-04 09:45 PM

I live in Florida too. Unlike most of the residents, I have somewhere to be, and I know when my blinker is left on in the left lane.
