RPM needle goes crazy !


Recommended Posts

I am not sure if anyone can help , but this is my problem :

Sometimes, i can see the RPM needle not moving smoothly upwards and bacwards, but no matter if you increase rpm, the needle stays eg 2000 and after some seconds it jumbs to the normal eg 3000. At that time, when you release the pedal, the engine's rpm goes down, but not the needle ! ...

The next day, everything works fine !

I think that something effects the movement of the needle and for sure is not the instument's plate...

Sorry for my English

Θα μποÏοÏσε να είναι ο αισθητήÏας στο κιβώτιο ταχυτήτων. Î’Ïίσκεται στο πίσω μέÏος του κιβωτίου ταχυτήτων. Όπως ένα μεταλλικό σωλήνα με ένα πλαστικό κλιπ αισθητήÏα. ΣπÏέι οÏισμένες WD40 για να βεβαιωθείτε ότι δεν είναι υγÏÏŒ στο εσωτεÏικό του.

Θα μποÏοÏσε επίσης να είναι τα Ïολόγια.

Unless the engine is physically revving to those rpms, it can't really be anything else.

Mine would stick at, say 4000rpm, when slowing down, so even when idling it was showing 4000 :-)

It would also move slowly occasionally and stick at all sorts of random speeds. Replacing the RPM driver really isn't difficult mate, if that's what it is....
