I am having a problem with my engine sensor fuse. Is keeps blowing? The car will start but will not idle. It will run if the pedal is depressed but as soon as it is released the car dies? I'm thinking one sensor is shorting but can't find Info on how to test the different sensors? Where would be a good place to start my search for a faulty sensor? Any info would help.

 

check out volvowiringdiagrams.com - you should be able to map from the fuse to the components on that circuit.
