Looks like you have a problem with your idle air control valve.

Double check your intae thottle plate for carbon and cleanout the idle air control valve and seat if there is a lot of buildup on that plate. That plate is what allows air to pass through freely at idle. If it is dirty, clean with warm soapy damp cloth. Make sure the cloth is damp and not soakng.

Check idle air control valve.

I'm having the same problem. At first I thought it was bad fuel so I replaced the fuel filter to no avail. Then I cleaned the Mass Air Flow sensor which also didn't work. Is your check engine light on?

This is the air control valve,did you hook up every ok .Recheck everything,all hoses,vac lines,sometimes these dont need replaced just an good cleaning out.

your IAC valve, idle air control valve is under the black plastic cover on the front right corner on the engine, remove cover undo valve, renew gasket and re install. ade 13 years volvo tech

YOU MAY HAVE A IDLE SPEED CONTROL VALVE PROBLEM, CLEAN IT FIRST, THEN DISCONNECT THE BATTERY, FOLLOW THE PROCEDURE I HAVE ATTACHED.

Here is the most common cause of this stall and idle speed issues, it is the idle speed control air-bypass valve and throttle valve, they get full of gunk over the miles and cause idle issues (stalls) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Try cleaning the throttle body and air idle control valve (IAC). The computer kicks the idle up when the a/c is on, if your throttle body or AIC valve is full of crud it will idle very low and feel rough.
