Darcy's Rare Volvo 740 hp
Except my Volvo 740 gl has the same problem as the 240, and my other Volvo 740 HP has the same as @volvodriverman , I think the purring sound is or could possibly be a worn turbo charger, and thanks @Tigabu , ill look into it :)
Looked at the FPR for the stumbles?
Not delved into mine too far yet, will test the fuel pressure first though;-)
Main pump fuse was blown but still shorting across, replaced it & its a bit happier, methinks its fuel pump time.
Reflow the solder on the fuel pump relay while you are at it.
I Wouldn't blame the turbo myself. I bet it's idle control valve hoses.irishbastard;12816 wroteExcept my Volvo 740 gl has the same problem as the 240, and my other Volvo 740 HP has the same as @volvodriverman , I think the purring sound is or could possibly be a worn turbo charger, and thanks @Tigabu , ill look into it :)
Got a new relay somewhere & will be replacing all the hoses soon. It feels lean to me but without a wideband (which is coming) I'm only guessing.
Ok awesome, thanks @Vee_Que ill replace the control valve hoses and hope that helps, and I'll try the In tank fuel pump, it could be an issue I think @volvodriverman
They normally run quite rich too assuming they have good injectors in them.
Hoses are impossible to buy as I found. I bet the other vacuum hoses will be average too. But unless I see the car in person I am only diagnosing off what you tell me not what it can really be
