Skispcs Posted January 3, 2020 Share Posted January 3, 2020 2014 Fusion with 2 Liter Ecoboost. Seeing 28 on LTFT, small numbers on STFT When I raise the idle to about 2500 the LTFT stays high. If it was a vacuum leak, I would expect the numbers to drop. I have checked for a vacuum leak but have found nothing yet. Attached a screenshot of data while idling at 2300 for 5 minutes. What else should I be looking at? 0 Quote Link to comment Share on other sites More sharing options...
