New engine or new vehicle ?
My 03 5.4 has 230k it’s already had its fair share of work done on it, I’m pretty sure I’ve spent $3k in parts alone over the past few years. Not a huge deal considering the average car payment that being said, let’s say I had to replace or rebuild the engine. That can run anywhere from...- Dmpsix

Acceleration non existent and high RPM's
Follow up question.... Let's say it's fuel injector related, because my guess it is. My brother in law has an expensive scanner and found there was something wrong with the way the fuel is being distributed. He told me what he thinks it is, and says it's likely my fuel injectors failing (sorry...- Dmpsix

Acceleration non existent and high RPM's
Pretty straight forward. Not sure if it's a vacuum/hose leak or maybe a transmission issue? Maybe fuel injectors? Spark plugs and ignition coils were changed two months ago with Motorcraft parts off Rockauto, fuel filter changed last year. April 9, 2021 - YouTube Right here worries me...- Dmpsix

I have no idea what's going on anymore
I haven't ran or touched the 2003 5.4 Expedition in roughly 2 years. Changed, o2 sensors, fuel filter, spark plugs, ignition coils, oil and ran some seafoam top engine cleaner. Cleaned out the throttle body, sprayed the MAF sensor and replaced the terminals on the battery. Car has a vacuum...- Dmpsix

Good catch, I'll update that and get that fixed up. I knew something was off, as you can tell I have no idea what I'm doing with this SUV. Thank you though.- Dmpsix

2nd Gen vs 3rd Gen
Early 2nd gen had the 2v in their 5.4's Other than that, they're basically all 5.4 3v What are the differences between the two generations? I'm considering getting a 3rd gen. But I'm also considering just getting a remanufactured engine and transmission in my 2nd gen when the time comes.- Dmpsix

How many miles on your 2nd Gen Ford Expedition?
Damn dude, I'm at 230k here. Had to replace water pump and intake manifold. I keep striking out with garbage quality ignition coil packs and have had to replace those twice within about 12-14 months or so. Other than that, everything's great.- Dmpsix

Upper Control Arm Bushings / HD Control Arm?
What do you mean? I just want it to ride like stock and as comfy as possibly. 2nd Gen Expy has **** tons of ground clearance. I think with the KO2's I'm already a damn near 12 inches off the ground.- Dmpsix

Annoying idle issues, might be transmission related?
It's more consistent the more I drive it. ANYTIME the car gets put into park or neutral, it'll rev up to nearly 3k RPM and just stay there until I put it in drive or turn it off. It's definitely a bad thing because the car jerks violently when I have to go from a 3k idle to drive. It causes...- Dmpsix

Are headers worth it?
After a bit of research, I doubt anyone has had a true successful conversion for LT Headers on the 2nd gen expedition. Shorty headers yeah, but shorty headers are basically a manifold, almost zero performance there. Someone reported that a RWD f150's LT headers may fit the 2nd gen, no idea if...- Dmpsix
