RPM goes high while shifting gears

Hi....
I have Nexia 1.6L DOHC (2000 Model). While shifting the gears, when I release the accelerator and push the clutch, the RPM goes high upto 2000 and this results in a sudden push when I release the clutch pedal. Please help.

Is your accelerator cable sticking/releasing slowly due to excess friction on it somwhere, or the spring being knackered?

No...........The Accelerator cable is OK.......very fine..........

lets separate between two things:

does it go up to 2000 when you release the accelerator or does it do so when you step on the clutch?

is it running @ 850RPM in idle?

To be very precise............the rpm goes high to 2000 when I step on the clutch..............

Yes..........its idle speed is 850 rpm.

one more thing......... when I press the accelerator during idling...... the rpm goes high (to 4000 for instance) but it comes back to 850 very slowly.............. it takes as much as 7 to 10 seconds to come back to 850 rpm.

Have you disconnected the battery or any sensors or fuses recently. Whenever I did on my Nexia I would have to wait a while for the ECU to go through the re-learn phase. The revs would take a while to drop but after about 50 miles of driving it would reset itself and go back to normal again.

Hi Turtle....

I do about 75 Miles Daily. and Neither i have disconnected battery or changed fuses.......... This problem exists from more than a year now.

If your stationary on an incline in neutral gear. When it ticks over at a normal 850rpm do the revs rise up a lot if you let the car free wheel down the incline in neutral gear without touching the clutch or throttle pedals?
