Can anyone help decipher freeze frame data please?
Should there be pressure with key off? Or should it be zero?- n.shift

I’m asking :) but i really don’t no what I’m asking for. Lol. You have anything to put me in right track to solve this leak condition on bank 1 and 2 with fuel pressure specs?- n.shift

But at higher rpm’s wouldn’t a vac leak be irrelevant? That’s why it’s inoortant to see at what rpm’s the light was set. I really need a obd2 scanner with live data . So what should fuel pressure be with key off, key on and running? I believe mine is the returnless fuel system- n.shift

Think a smoke test would find a small leak?- n.shift

The freeze frame data should point you in a direction of vaccum leak or fuel/sensor related. But I’m uncertain which- n.shift

Fuel filter was changed as part of routine maintenance about a year ago. I’m thinking vacuum leak because if you look at rpm, the code triggered at 868 rpm. My obd2 test doesn’t have live data. I can find any vaccum leaks. I’m going to smoke test it soon. But I’m thinking I take gasket because...- n.shift

2001 expedition p0171 p0174 WITH LONG CRANKING TIME
I could very well have 2 problems at once. I’m really leaning toward vacuum leak for the p0171 and p0174 codes because if you look at my freeze frame data,the codes where thrown at idle. But again, I’m just leaning. More research is needed. The check valve in the pump might def be the problem...- n.shift

Stumped on Roaring Noise
Not sure about the noise. But def sounds like a bad bearing. Perhaps you changed the wrong side. I always change both sides at same time- n.shift

The freeze frame data is suppose to point you in one direction or the other. Here are my results any ideas? Suv runs great. Starts normal 99.5% of the time. Very long cranking time the othe .5% of the time. Plenty of power. Doesn’t die or doesn’t run rough. Just the 2 codes and every once in...- n.shift

Could it be tire noise? Rotate tires see if that helps. 4x4? Bad axel?- n.shift

Are you saying weak fuel pump do to the freeze frame data? I’ll check my fuel pressures soon. Filter is new- n.shift

I have a 2001 expedition with codes p0171 p0174. Sometimes but not always, It also has long cranking times before it starts. once its running its runs great. its 5.4 L 117k miles. Any thoughts on this? thank you I forgot to mention it only does this when cold. when I say cold, I mean 30 degrees...- n.shift

I forgot to mention it only does this when cold. when I say cold, I mean 30 degrees outside. Im thinking leaking intake gasket. Because when its warm, it doesn't do it. maybe do to the rubber gasket being slightly swollen...but any input would help- n.shift
