    1999 electrical issues

    You would be best off replacing the GEM. Also, you can do the brown wire mod to get rid of the 4x4 cutting in/out on its own

    Multiple failures at one time!

    Have a new key made. Get 2 made for the hell of it. It is very rare that the ECM will fail on these. If anyrhing it would be your GEM that would fail. I got my keys from carandtruckremotes. They have OEM Strattec keys available for a good price. My Ford dealer even cut them for free. I would...

    P0171/P0174

    Hamfisted, that is my next step here; however any vacuum leak I have dealt with has been the exact opposite as what I am experiencing here. With every vacuum leak I have encountered, it has been lean at idle and fine at a load. My issue is lean under a load and OK at idle..

    P0171/P0174

    I just bought a 01 Navigator with 130k miles... Been stting since 2016. I just replaced the fuel pump with a Delphi unit. I did not drop/clean the tank. I am getting 171/174. Something to note here is that the fuel gauge turns off/on. At idle, bank 2 is very lean around +20 LTFT . At idle...

    00 4.6 NPI intake on a PI crate engine

    I would recommend powertrainproducts. I have not personally used them, but Fordtechmakuloco has recommended them in the past. Someone else may chime in here.

    1999 electrical issues

    car starting by itself is definitely GEM-related. Can you verify your build date (pre or post facelift) Have you verified there are no vacuum leaks at the actuator? You can use a disposible vape with a tube as a smoke machine to see. Also, have you verified 12V at the transfer case motor...

    Opinions Please 2006 Expedition Limited

    Gary, I am going to disagree with you on your comment. Computers have come a long way, and arguably all of those failures you experienced are not very critical components of the vehicle. I have never once had a PCM or GEM break on me on a Ford. Now, my Jaguar on the other hand..... that thing is...

    HELP - timing chain fell off

    That's part of your phasor. For your chain to have that much slack the tensioners are shot. Fordtechmakuloco is your man for these 5.4 3V engines. From the picture, the chain is still on, DO NOT ROTATE THE ENGINE CCW. If this were my rig, I would take all timing components off and replace them...

    Ways to add MPG in a $$$ Gas Price Economy!

    decat ur engine, installing a larger valance would yield better mpg. lowering your truck, regear your rear diff/front diff if u have one. unplugging the fuse for the front diff actuator would keep you in 2x4.

    Blend Door Help

    That **** was awful, man but if you had power tools and honestly just break the majority of the plastic you'll be good. If you want to replace the blend door itself, you need to cut the plastic out by the glove box. I already had it fixed in ~2011 so I just went ahead and replaced it with a...

    P0171 Bank 1 Too Lean - Decatted O2 Sensors?

    Hey everyone- A little backstory: my truck is decatted (has the pre-cats still) and has the rear O2 sensors mounted in spark plug defoulers to fool them. I got a lean condition code on the way back from work today, and was wondering if this could be the cause. If I recall correctly, the rear...
