Okay here's the deal.... I just finnished hooking everything up... i have a new fuel pressure regulator.... But when i start it idles at 500rpms then when i rev it it dies can anyone help me??? I dont know what it can be i just got a new bac valve for the s4 and we put the s4 tps on... Any ideas please??

 

make sure the fuel line has NO LEAKS what so ever and your radiator hoses are completely intact. Mine did that... I dont know what the radiator had to do with the problem but i bought new tubes and it worked perfectly... ??
