Rpm jumping

03 lx ody 85,000km, when idling the RPM are irregular. Anyone ideas?
Thanks.

It could either be an IAC valve going bad or the connector on the power steering pressue switch has broken wires. they break right at the conector were they go into the rubber weather seal.

thanks for reply, where the IAC valve located?

On the bottum side of the throttle body. It has a few small collant lines going to it.
