Engine Studder, No Codes
This may not be relevant to your 7-minute problem but... I had a P0304 in 2018, fixed it with a new, aftermarket COP. But soon after another coil on the same bank failed and eventually all 4 on bank 1 went bad and were replaced. Then the fails started repeating on the new COPs. Cutting to the...- jr1under

FORSCAN on Gen1
I can answer only a small part of your questions but this Mode $06 data is a test of the EGR hoses.- jr1under

Cleaning throttle body to EGR valve passageway
The picture of the intake was before cleaning it a few years ago. Hadn't gone beyond that though which is why the surprise at how relatively clean the other parts looked. All I ended up doing was spray cleaning the EGR and reinstalling it. And losing a 10mm socket.- jr1under

Cleaning throttle body to EGR valve passageway
Is this the bolt that broke? Your situation is the worst, inspecting what turns out to be a non-problem but breaking something else in the process. How to turn an hour into three days.- jr1under

Cleaning throttle body to EGR valve passageway
Gotta admit, I had to look up what a pintle is, learned it's sometimes paired to a gudgeon. Still not exactly sure so I'm posting multiple pictures. The EGR came off easier than expected, nothing was corroded in place. It also looks way better than expected considering how bad the TB intake...- jr1under

Cleaning throttle body to EGR valve passageway
Haven't done it before but suppose I can inspect one end of it by pulling off the EGR valve. Would have to do that anyway if the whole TB assembly needs cleaning. Pulling out the assembly seems simple enough but I'm always leery of unintended consequences when doing something for the first...- jr1under

Cleaning throttle body to EGR valve passageway
Let me restate the question... I've read a lot in this forum and elsewhere about P0401(Insufficient EGR Flow) in Gen1's. Consensus is the first fix attempted should be to clean the throttle body and its passageway to the EGR valve. Is it worthwhile to clean the passageway now even though...- jr1under

Stuck oil filter
That's a great solution...if you checked that the filter would loosen before draining the oil. I never have but will from now on!- jr1under

Cleaning throttle body to EGR valve passageway
Picture of 5.4 throttle body before cleaning it 22k miles ago. The TB-EGR passageway has never been cleaned and I'm assuming it looks as messy or worse. So, even though there's no codes or other trouble indicated, would you clean it anyway?- jr1under

Stuck oil filter
I got these oil filter pliers years ago after starting to DIY maintenance. Needed them because my 5.4's filter is so awkward to access. Is the 4.6 worse?- jr1under

Stuck oil filter
When I was a kid working at my father's service station, we used a screwdriver too for filters that wouldn't come off but that doesn't work very well with the construction of modern filters. Could you wrap it with duct tape and leave a long tag end to pull on for more rotary force?- jr1under

2000 Expedition 5.4 throwing codes for all 4 o2 sensors. Sensors already replaced and still throwing code
Apparently, the culprit isn't/wasn't the sensors themselves but their power source. Hamfisted pointed out the likely suspect.- jr1under

2000 Expedition 5.4 throwing codes for all 4 o2 sensors. Sensors already replaced and still throwing code
According to the OBD SysOp manual, those faults happening immediately after starting the engine indicate a voltage problem. As it's occurring on all four circuits, maybe there's a common power source to blame.- jr1under

2000 Ford expedition Drive Cycle
One of the criteria for the tests to start is the engine must have been running for more than 5.5 minutes. I don't think it matters whether it was idling or traveling before then.- jr1under

2000 Ford expedition Drive Cycle
Just curious...now that the P0174 is gone, what does the scanner show for Long Term Fuel Trim - Bank 2? The link below is to the OBD SysOp manual for your 2000. Starting on page 11, it describes the criteria required for the EVAP test to be completed...- jr1under
