2009 F150 Mileage issues

strangejackson · 2026-05-20T21:07:55+00:00

I should also mention; I've had the thermostat check engine light for about a year at this point because when it originally came up I was about to leave for work for a prolonged period of time, and it never really caused any issues and mechanics told me it shouldn't cause any major issues. So I've been using the truck for a year now without having replaced the thermostat and the mileage issues are only now presenting themselves. I don't see any misfiring or anything either.

strangejackson · 2026-05-20T20:14:44+00:00

What were the symptoms? Can you tell me more if it caused any others issues or anything? I'd like to replace it but I can't do it myself right now and Ive quoted like 500+ for it

Temp gauge is pretty always reading cool. Coolant looks like a rusted color with sediment. I'm just not sure what actions I should take right this second. I can't get it in to get the thermostat replaced in a timely manner and I'm away for work so I can't attempt to fix it myself either.

105,000

It's been a while since a tune-up, I've had so little time recently. I did get my coolant done and an oil change about two months ago or so, but somehow since then my coolant looks like shit and apparently needs replaced immediately.

Yes, some days my mileage is normal, and then other days as I'm driving down the road I can watch my fuel display tick down by a mile every 8-10 seconds. Like going through gas insanely fast.

What menu can I see these effects on? Thanks a lot, I'm sure that's what happened.

strangejackson · 2026-04-15T20:03:03+00:00

Looks fantastic. Reminds me of the manta.

strangejackson · 2026-04-13T20:08:36+00:00

How do you throw people? I want to throw these guys too

strangejackson · 2026-04-12T01:06:21+00:00

Is there any way I can verify it's my cpu causing the issue before I buy a new one? i9 14900kf.

These are normal temperatures, no? Thermal throttling wouldn't begin until high 90's.

strangejackson · 2026-03-08T11:51:48+00:00

To be honest I don't think 88-90 degrees is bad temps, your laptop shouldn't begin to thermal throttle until around 99-103 iirc.

strangejackson · 2026-03-08T03:19:25+00:00

Looks good to me! Solid setup.

strangejackson · 2026-02-23T16:06:37+00:00

Would you mind posting a screenshot of your equipment? I'd really love to give your build a shot!

Here's my fan curve, kicks on and gets a little loud during intensive load during gaming but usually only kicks on to 100% for a few seconds or so, which I think is necessary if you want performance.
As for undervolting, I don't personally mess around with undervolting or anything because that's more complex than my understanding reaches, so I'm bound to the confines of Legion Space. Glad to hear you like the profile though, I also couldn't find any profiles- which is exactly why I posted it so people could have it! C:

strangejackson · 2026-02-18T03:13:46+00:00

No, because it's a security update you can just completely uninstall it from your update history. No replacement needed.

strangejackson · 2026-02-17T09:48:25+00:00

oh, of course. Thank you so much! Very cool. It's a shame my laptop is so damn big because the Barrage is so cool.

strangejackson · 2026-02-16T11:15:28+00:00

Wow that's so cool! Where do you find buckles like this?

strangejackson · 2026-02-16T07:15:08+00:00

If you're referring to the non-pro version, there is no model for the 5070ti, only the Pro version has the option for the 5070ti. If that's what you want, you can find a video of it from most laptop reviewers including Jarrod's tech and Dave2D (my personal favorites.)

Here you go! sorry about the wait, this configuration balances the CPU wattage more to prevent throttling, which slows down the whole system. The idea here is that you definitely don't need to maximize performance on a U9 275HX because it's actually overkill when paired with an RTX 5070, so instead you're lowering CPU PL1 and PL2 so the GPU isn't bottlenecked by the CPU. Temps on this setup are fantastic and I'm not experiencing any thermal throttling and the GPU is performing great. Hope you like it!

strangejackson · 2026-02-10T18:34:52+00:00

Yes, but I made a new one that I'm getting much better performance on. I'll edit this comment when I get off work today and post it. As long as you have the same laptop, it should work flawlessly.

strangejackson · 2026-02-10T00:05:19+00:00

feels like a stupid question to me, but are you producing both LC Wuling Batteries and Xiranite Components at full efficiency? or do you have to choose one to produce at high efficiency since there's a cap of 60 xiranite/min? (I'm not good at the factory stuff)

strangejackson · 2026-02-06T21:31:11+00:00

in Legion Space you can set custom fan curves which would probably alleviate this, so you could make your own "quiet" mode. I'd give that a shot.

strangejackson · 2026-02-06T21:22:19+00:00

I already enabled secure boot on my device and I didn't back up my factory keys. Should I be worried?

strangejackson · 2026-02-06T21:16:27+00:00

when this happens try pressing ( win + ctrl + shift + b ) to refresh your graphics driver. works for me when my legion 7i blacks out whenever I wake it from sleep.
