moving the foot from
the accelerator pedal"

Hi! Thanks for the advise but this is not the case. Speed control is essentially "cruise control" feature that I do not have have in my car. I'm gonna drop a new MAF today and see if this fixes the issue.

On a side note I've found that turning off AC helps a lot with the issue. I remember somebody with the same issue already found this side effect. Interesting.

The ECU will increase the idle speed when the A/C is on to account for the additional load and keep the RPM's at the normal level. This seems to accentuate the problem that you are experiencing.

Good point, thanks!
