Engine stalling at idle speeds

[Wishodha]

Hi 

My car is Nissan Fb15 2001 ,1500cc, Auto gear.

The issue is engine tends to stall at idle speeds.

I got done a engine tune up and air flow sensor clean up 3 days ago. Initially it seemed okay. But again problems started. It also has a 'miss' with a concurrent blink of the 'CHECK ENGINE' indicator, this also happens at idle speeds (not in decent higher speeds, at all.)This is worst when I take a sharp turn with A/C on(like in a roundabout) , and the engine stalls completely. when I inspect it at parking when the A/C turns on automatically, the engine almost shuts down and again turns on. 

Where could be the error? Whom should I meet?

you might want to check your vacuum hoses and the fuel pump. Engine could be starving from fuel under heavy load at low rpm. 

How are your spark plugs and MAF?

Also you might want to check your EGR. 

Nishantha down attidiya bakery junc is a good mechanic to diagnose problems but he is a little pricey. ($$$)
