PAH Donating Members 361 Member For: 16y 1m 12d Gender: Male Posted 03/08/18 02:39 AM Share Posted 03/08/18 02:39 AM 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 Link to comment Share on other sites More sharing options...

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 Link to comment Share on other sites More sharing options...

Once cleaned, the issue disappeared. Food for thought..... Link to comment Share on other sites More sharing options...
absmith New Member 18 Member For: 16y 10m 16d Posted 05/08/18 05:29 AM Share Posted 05/08/18 05:29 AM 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.

PAH Donating Members 361 Member For: 16y 1m 12d Gender: Male Posted 09/08/18 10:27 AM Author Share Posted 09/08/18 10:27 AM 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.
