August 3, 20188 yr #1 Guys, My 2008 FG XR6T is stalling at idle. It's running fine everywhere else. It's just had the following replaced. Fuel filter. Coil packs. Oxy sensor. Plugs. I understand that there are a few gadgets close to the throttle body to assist with smooth idle and I wonder if they might be the cause of the intermittent stalls? If you've had experience with the issue please let me know. Even better pls send me a few photos. PAH
August 4, 20188 yr #3 I dont know what else you may have changed on yours, however I did have idle issues when I first started modifying mine. I had an issue with my FG XR6T after fitting a bosch 044 fuel pump and surge tank, it is manual so every now and then it would stall with the clutch in rolling to an intersection. Took me a while to find but it turned out the fuel pressure was around 6 bar at idle (this is some years back so I may be a little off here). The factory fuel pressure regulator could not flow the extra fuel delivered by the 044. Replaced the regulator with an external regulator and all good since, https://www.efisolutions.com.au/turbosmart-fpr1200-fuel-pressure-regulator-black
August 5, 20188 yr #4 I had similar issues and found that the filter screen in the regulator was almost blocked completely with contaminant. Once cleaned, the issue disappeared. Food for thought.....
August 5, 20188 yr #5 Interesting, I never noticed a screen in there when I pulled the old regulator out. I have heard of some people somehow opening up the factory regulator to flow a bit more. Took me a while to find because the problem began once I brought it home from the tuner (they fit the surge tank and 044 while tuning), went back to them 3 times and when they still didn't know even after changing to different injectors, I bought HP tuners and started hunting the problem myself. Easy job to put a pressure gauge on as a quick check. Correct me if I am wrong but at idle I think you are looking for 4 bar fuel pressure.
August 9, 20188 yr #7 Author Thanks heaps guys, So where's the photos of the fuel regulator ... and instructions on removal. ;-) Is the fuel regulator the gadget on the inlet manifold so close to the fire wall that you need the fingers of a contortionist to remove it? It's held in by a circlip? If that's it I've already replaced it with a new unit from Ford. If it's NOT it somebody please point me in the correct direction. Thanks again. PAH
