    Can anyone help decipher freeze frame data please?

    Should there be pressure with key off? Or should it be zero?

    Can anyone help decipher freeze frame data please?

    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?

    Can anyone help decipher freeze frame data please?

    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

    Think a smoke test would find a small leak?

    Can anyone help decipher freeze frame data please?

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

    Can anyone help decipher freeze frame data please?

    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...

    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...

    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

    2001 expedition p0171 p0174 WITH LONG CRANKING TIME

    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...

    Stumped on Roaring Noise

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

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

    Can anyone help decipher freeze frame data please?

    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...

    2001 expedition p0171 p0174 WITH LONG CRANKING TIME

    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

    What rear differential do I have

    fluid is like new and full. transmission had complete rebuilt around 30k miles ago. doesn't the torque converter usually make that noise while cruising in overdrive? I heard to test that is to turn over drive off and see if noise goes away. Im about 100% certain its coming from the rear...

    What rear differential do I have

    did your only do it when it warmed up? If its a cool day, or cool rainy day, its as quite as a mouse. it only makes the noise the warmer it gets. but after a long drive, the rumbling gets pretty loud..

    What rear differential do I have

    so this leads me to me next question. when I accelerate from a dead stop and turn left or right, I get a rumble strip sounding noise. If I accelerate from a dead stop and go straight, I get no noise. Sounds like coming from rear diff. but Im not positive. do you guys think this is the LSD noise...

    What rear differential do I have

    i have a 2001 rwd Eddie Bauer Ford Expedition. 113k miles with ruble sound when accelerating from a stop and turning left or right. No rumble strip sound when going straight. I read where it could be the limited slip differential. My door jam sticker is missing. But I have the toe tag off the...
