Hi all,
I have a questions related to sudden RPM jumps which I recently observed
. The thing is that driving 120 km/h on the straight highway using the
same tires and carrying the same load the rpm are different. Usually I'm
getting 2600 RPM but sometimes I can get 3000 or 2800 for long time but
it can just suddenly jump to lower value. The odd thing is for example
that whet the RPM are at 3000 (I'm talking about driving 120 km/h for
some time so the engine is warm enough) i reduce the speed and
accelerate again and the RPM goes to 2600 at same speed.
To be honest I can't hear the difference in RPM so I'm suspecting that
it might be some RPM measurement malfunction. (or maybe I just hope it
is ...: )
I checked the RPM gauge buy replacing it with friends and I got the same
result. One option would be that the RPM sensor is malfunctioning - but
I would expect that it would occasionally drop to 0.
Any ideas what might be the reason for RPM jumps ?
Regards,
Tomaz
