Try cleaning it mate, also try cleaning the IAC/AAC etc. Also clean the carbon around the thottle body.

has the car had auto to manual conversion?

i've heard that if the wiring for the auto isn't changed properly, a Idle/hunting Probelm can occur. Disconnecting the AFM just puts the car into Limp/Safe mode so probally changes the characteristics altogether.

But yeah cleaning AFM could be a start, just use electrical contact cleaner. Just don't touch the element and also removing the wire mesh isn't recommended.

yeah disconnecting battery and turning on anything that will draw power (eg brake light) to use up any existing current in the ecu is prob the easier method to reset it.

AAC = auxillary air control, Situated on back of plenum near the firewall.
