You'd have to be running really hot or have a faulty sensor for this to happen Link to comment Share on other sites More sharing options...

Running hot is definitional not causing it as it's happening only when cruising.Faulty sensor? Maybe but not likely as it only happens for a very short period of time, it happened to me few days ago again and I press the clutch and lift off the accelerator to see if it will stall and it ran perfectly fine. I don't think a sensor would stuff up for 2 or 3 seconds and go back to normal again, but I could be wrong. Link to comment Share on other sites More sharing options...

You may find the issue goes away if you're installing a new pump, however better to get it fixed under warranty. Link to comment Share on other sites More sharing options...

So this indidcated that there was a problem when the car was in closed loop cruise mode, turned out to be a falty O2 sensor..Heres my thred on it..http://www.fordxr6turbo.com/forum/index.php?showtopic=46294 Link to comment Share on other sites More sharing options...

The best thing now is I can flash my car soon as my flash tuner comes Edited 21/07/08 10:46 PM by SILK RSPEC Link to comment Share on other sites More sharing options...
