Mazda 323 Auto Idling problem
Hi all, new on here. I wonder if anyone has experienced a problem similar to mine. In normal idle it is fine, just sits there at just under a thousand revs, but when it is in drive and the car is stationary, the idle is all over the place and the engine stalls. Thanks in advance.

What is the year and engine type you have?
Assuming that your engine is nicely tuned up (plugs wires, airfilter etc) it is most likely an issue with the idle speed control. The ECM should realize that you are in D and should raise the idle speed in response. So look at all electrical connections near the throttle body and also at the transmission. Some times it is enough to disconnect and reconnect the harnesses.
If your engine needs a tune up, well, just do that.

....and check if the air intake hose is cracked. When you put it in gear the engine will tip a little and jank on the air intake hose. Any crack there could open and cause the rough idle and stalling.
If it is cracked use duct tape.
