Hi all,
(2013 F150 3.5 )
I have some oddities with fuel trims. While idling my STFT stay close to 1.00. When I hit the AC they can climb up to 1.20 but then slowly settle down. My LTFT is usually around .93-.96 while idling. When I am cruising it gets higher to around .95-.98 but when I start hitting boost they both are around 1.00.
Would this indicate a vac leak? While idling I am about at 17-20 in/hg (Mind my elevation: 5200+/-) My AFR (lambda) is around 1.00 while idling sometimes jumps up to 1.05.
Is this acceptable or do I need to grab more info?
Thanks for everyone's thoughts!
(Just cleaned all MAP sensors)
