Hi! I have a 1994 volvo 940 turbo.
It was running fine, but today, when i get to a stop light, the engine shuts off.
Could it be the fuel pump relay?
Catalytic converter going bad and clogging?
Turbo going bad?

I would appreciate the help.

Thank you.
Hector.

 

Relay, yes, the others, no. Also check and clean the Idle Control Valve.

 

Does it restart? Have you checked codes?

 

Oh!
I will check the idle control valve.
Thank you lev.

Swiftjustice44, how do i check the codes?
Thnk you, swiftjustice44.
Hector.

Could it be: Vacuum hoses?
