Hi guys, I'm wondering if any of you guys can shed some light on my problem I am having with my XR6 Turbo Ute. Ute surging on hwy, runs very rough at idle sometimes and either stalls or tries to take off on it's own like you have accelerated, sometimes when I go to accelerate normally nothing happens and then all of a sudden it takes off madly, blows heaps of black smoke when idling rough, and using lots of fuel. I have been checking sensors, vac leaks etc and have checked my O2 sensor against Miss Aly's and found the grey wire has a dead short where as Aly's has not. Could this be my problem. Ford have been no help at all!!!! They first told me to put everything back to standard ( I had plumbing, pod air filter, larger injectors, edit, modified exhaust) I do as they wish and leaving the larger intercooler in place and I take it back to Ford and as soon as they see the larger intercooler they say that's my problem. PRICKS!! So I have decided to try and fix it myself. Mind you I have been to 3 Ford dealers about my problem. The ute does the same thing on the ford std tune with std injectors as well as on the edit tune with large injectors. I would appreciate any thoughts on this, thanks Guys. Regards Brian.
