System lean in bank 1 - P0171

Just to let SCWICKEDSTANG know, someone saw the trouble I was having and bought me a new maf sensor and had it installed and they erased the error codes on my van. I think they think that is going to fix it but I have been replacing maf sensors on my van since 2018 and the error keeps coming back. The same ones P0171 and P0174. And by the way I have been driving my van and so far it hasn't been any new codes set as of yet and it still runs good so far. Also, A new maf sensor was installed not to long ago too and it didn't turn the service engine soon light back off either. It still shines so pretty and annoying too. Lol But I will let you know as soon as I can. Looks like I will have to find a shop that has a smoke machine etc.

Hey Ken and BMDouble thanks for the information. I will see if someone will do this for me. What both of you said to try etc But if the intake has to be replaced it will have to wait. I can't afford to have that done now. Sad to say etc Also, I got tired of waiting on people to help out with the smoke machine so I tried what SCWICKEDSTANG said and clear the codes but before I did clear the codes I put in another mass air flow sensor in there. A new one that is. Well the box to the thing said it was new anyway etc. But I notice something on the old mass air flow sensor I pulled out of there. Someone wrote the word "good" or what ever it is they wrote on the bottom of it. Like they kind of engraved it sort of. And it had a red mark of some kind like they had marked it for some reason. Like a red dot on it. Now that may not mean anything but that's the condition the old mass air flow sensor was in when took it off etc. Well anyway, the check engine light is off for the moment now. I will post the picture of the mass air flow sensor up. As soon as possible so you can see it for yourself etc.

Here's what it looked like the mass air flow sensor we took off ourselves. Plus it was a remanufactured one too. I had a brand new one on there before the repair shop replaced it with this one.

Oh, oh okay. I didn't know that. About how the junk yards operate. Thank you for the information Alex on how the mass air flow sensor works too. I have a can of CRC mass air flow cleaner. I had sprayed it on the sensor I posted up there at one time but the error code came back. I drove it today and it ran really good and the service engine soon light is still off where I cleared the codes. (I believe the Lord fixed it for me myself. People laugh at me when I say that. But I believe he did.) The funny thing is I am so used to it being on. It looks funny it being off, lol. Not that I am complaining it being off etc. Well anyway, if anything else comes up I will keep you guys posted. I just wished I had a scan tool that does live data so I could read the computer while it is running good and not producing any error codes.

Lean burn code PO174.

Thanks again guys (SCWICKEDSTANG, Ken, BMDOUBLE) for all of your help!

Thank you DMDOUBLE. Also, I posted something about my van door on here but I don't see what happened to it. I have that fixed now. I tried to delete the comment but it won't let me get to it.
