Hi folks,

I'm having a rather odd issue, i have read around on the forums and tried idle resetting, spark plug changes, throttle body clean etc but not getting anywhere.

I have a 2.4 K24A Stepwgn 2005 CVT. So the issue is roughly after 10 minutes from car starting I get a momentary surge in rpm, I might be in P and the rpm drops from say 750 to 500 and then back up or i might be in D at a junction.
This happens maybe once or twice and not again for the rest of the day. No codes and has been happening for a few months now.
It seems to consistently happen around the 10 minute mark since the first drive of the day.

I have noticed sometimes there is hesitation in the gear change while driving.

Any advice appreciated.

Thanks,
