My 1991 740 volvo turbo doesnt start specially during the morning.Is it comes with a cold start valve?
There are several things that can cause your 1990 Volvo 740 to stall while driving. The most common cause is a bad fuel pump.
It is below the throttle body, mounted in a rubber bracket. Follow the 3/4 inch hose from the air filter box. it goes to IAC valve.

The "PCV" valve is actually called the "flametrap". Its located on the driver's side just behind the intake assembly. If you go to www.brickboard.com they have a great FAQ just for the 700 series Volvos.
