Vios Rpm Issue

[cecilio]

Hi

my vios 2004 (first generation) give some strange RPM reading recently. When i drive highway for constant speed of 80km/h and the RPM reading is at 2000 rpm. I know this is bit high as previously i only got < 2000 rpm for 80km/h.

I can hear the engine also bit more noisy.

Does anyone has face this problem before and please advice how to rectify it ?


Thanks.

cruising @ 80km/h the torque converter should have locked up and your reading shouldnt change. when's the last u changed ur ATF?

Check your torque converter...is it in good condition or not...

good one chinozie! I am confused by one of the points tho. It says if you can slow down in neutral without the engine stalling the converter is at fault? How is that even a problem? or am i missing a point here... :hmmmm:

errrrrr...yaa lor...
I often do that also...put into "N" drive while slowing down to a red traffic light without stalling...

hmmmm...I think it's the other way around...slow down n stall...i think...

Will cause such problem if change gear to N while approaching a red light and stop the car? I usually do that...free the gear and control the brakes to put the car into a full stop slowly...
