I have engine idling problems. The engine rmp sometimes goes up and the then comes down. This happens mostly when I switch on the AC and when I start it on the morning.
I did a tune up and it is still the same way. Is there something I can do to get my idling stable

You should check your Idle Air Control Valve ( IAC ). It is set on you throtlle body,near the TPS ( Throtlle position sensor).
