spectral Forums Junkie Location: Brisbane Registered: February 2003	Re: GT4 cutting out Sun, 25 July 2004 07:49 it makes life easier if you do pull off the intercooler, gives you a little bit more room to work. With respect, if you don't know the section I mean, when I say AFM and intake pipe, then you probably might have trouble solving this problem.. but anyways... Loosen the clamps from the turbo inlet, and also at the AFM outlet. Disconnect the other hoses, and lift the pipe out. You can now see the wastegate actuator. It has two hoses coming off it. One to the turbo housing, and the other runs back behind the engine to the Turbo VSV. Take off the one that runs to the turbo housing. This is where you apply the ~10psi of positive pressure. Don't exceed this by much as you can cause damage. If the rod that runs from the actuator to the turbo exhaust housing moves, then the actuator is fine. But yeah, check the Turbo Pressure sensor on the firewall first. You can replace/test this very easily without removing a whole heap of stuff. Verify that this sensor is working correctly before starting on the rest of the stuff above. \ Check it like this: Pull out the plug and turn the ignition to ON (don't start the car).. measure the voltage across the outer two pins.. it should be between 4 and 6 volts. Now connect it back up and start the engine. Measure the voltage across the middle pin and the pin closest to the firewall. If the car is idling normally, it should read around 1.2V LESS than it did before. If it checks out OK, then try looking at the wastegate as detailed above. If the voltages look strange, then borrow another persons sensor and plug it in and see if its better. [Updated on: Sun, 25 July 2004 08:00] [Report message to a moderator]
