revs climb between changes

Lift off throttle to change and revs climb slightly rather than drop, as if the throttle plate is lagging behind the pedal a bit.

Could be:
- sticky cable
- sticky throttle
- dodgy TPS

?

Anyone else had this sort of thing?

Doddy did you by chance just add a cold air intake ? Sounds vacuum related.

thanks for replying dude - nope: no messing at all.

This car has had Honda servicing all it's life and hasn't been modded at all. The air filter in there is a bit dirty but not terrible. Will see after I change it and the fuel filter. I'll have a go at the timing after that.

If it does it a lil then its normal. Its so you dont kill the synchros in the trans. Its normal dont worry about it. If on the other hand it goes up and stays up for a while then goes back down to idle you got an issue. An intake wouldnt do that btw.

Mine does that too, but not very often. Usually when its cold.

Does yours do it always OR intermittently? I'm trying to figure it out, it's not related to your filter tho.

You are correct about the intake not doing that BUT, When i put my cai on i removed some vac lines and the rpm's would rise when shifting, more like never dropping down.

well I bought a nice roll of braided vacuum line last week, so when I get the fuel filter in I'll tinker around the engine bay replacing hoses.

Gotta question first time driving stick? Sometimes first timers engage the clutch quicker than lettin off the throttle so there is a slight shift up in rpm. Dunno seen some people do that.
