I didn't see the Walker maf sensor as an upgrade but more of a replacement seeing as the housing stayed the same size. Am I missing something??

https://www.amazon.com/gp/product/B00T1BXZ6U/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 This is the MAF sensor I bought.........

So Ive waited a few days to post this..... I wanted to be relatively sure. Saturday evening I tried something.....I put the oem MAF sensor back in and removed the Walker aftermarket one I bought. It instantly fixed my fuel trim problem. 3 days later and the short term trims are fine and I have...

I am now getting CEL for lean on banks 1 and 2........fml

So I've been having trouble running lean lately and everytime I think I have it licked.... it rears its ugly head a little differently. As of the last 2 days it predictably runs slightly rich in the morning when it's cool outside, and super lean right about noon when it's in the 80s. Just...

Thanks for the reply! I had a custom tune done and it helped a lot.... still in the low 90s at idle but I'm not getting a CEL and the car runs fine. Thanks again!

Using my SCT X4 to monitor a few things I'm noticing that my fuel trims at idle are lean. While driving around they hover right around "1.00" +/- .03. However when I come to a complete stop they nosedive to "0.80" , then go back up once I start driving. 1999 Explorer 4.0 SOHC, Car is running...

Update: Solved. Had a vacuum leak where the egr went back into to intake manifold. Hopefully this will help someone else in the future.

Thanks, I checked fuel pressure yesterday in fact (bought a kit from Advanced Auto Zone). Was right around 65 PSI. Thanks guys.

Yep.....that definitely DIDNT work lol. The cable matched perfectly and was identical.....except it was about 4 in short. Too bad......junkyard it is I guess.

So I had a custom tune done for my explorer and it came on the SCT X4. While datalogging I noticed that my fuel pump duty cycle stays at 1%.....always. Is there a sensor or relay associated with this? Sign of a failing fuel pump? Thanks in advance.

Well I ordered it anyway.....hopefully it will work or maybe with some modifications. I'll let you know when it comes.

So after doing some research the prefix (the first 4 chars) are just information about when it was released into production. How to Decipher FoMoCo Part Numbers - Overview - FORDification.com With the basic part number and suffix the same this should work just fine. Thanks Red.

That's for the ranger 2.5L I4. It looks the same.....the length may be different. It might be worth a shot though.

Yea, that's what I was afraid of. Not that I mind a junkyard item but if I'm going to the trouble to replace something I sure would prefer it to be new

My throttle cable is stretching.....I've gone from 1 zip tie to keep it taut to 3 in the last 6 months. I can't seem to find a replacement anywhere, OEM or aftermarket. XL2Z9A758AA is the part number but obviously has been discontinued. Can anyone point me in the right direction?

Sooooo....I have been fixing up this old explorer. Started with a K&N Filter, Ford racing throttle body and swiss cheese mod on the air box. After putting the Screamin Demon Coil pack, plug wires, and new plugs in, everything ran great. Much smoother. This past Weekend I put Gibson headers and...

Great news.....nothing to replace LOL. Thanks a lot!

While changing rear differential fluid I found this black box with "To cannister" followed by an arrow written on it. What is it and do I need to fix it because it looks disconnected. Thanks in advance.
