    remote start not working

    Certain pending codes will also disable it. I'd pull DTC's using ForScan (or a good scan tool) and see if anything pops up.

    What grade of gas do you put in your ST?

    Dealers aren't really the most reliable when it comes to technical advice. Regardless, the topic of fuel is in the owners manual. Really it's the yellow highlighted section that folks are debating here regarding a stock, untuned ST. On a 95 degree humid day, if you are towing something...

    Did the horsepower change on the 3.0L

    2020-2021 Platinum was 365HP/380TQ

    Did the horsepower change on the 3.0L

    My thought as well. I'm an engineer and I spend a disappointing amount of time reviewing and correcting incorrect technical specs in our marketing materials. The spec page had two typos. HP, and both the ST and Tremor got 3.58 final drive ratio, not the 3.31

    Sound deadening options

    I did it to one of my Mustangs and it was an extensive project. I had the interior out, so everything was done. Firewall, floor and trans tunnel, roof, all doors, trunk, etc. Did it make a difference? Yes it did. Do i have measureable data? No, but i can tell you with the windows up and AC...

    Throttle body upgrade?

    I'm curious if it needs tuning. I have no plans to install one however. I know when i change throttle body size on my Mustangs (N/A setup if that matters), i need to make some slight adjustments to the tune for drivability.

    Errer - "Pre-Collision Assist not available" - Need guidance

    Before you disconnect the battery I'd hook up ForScan, or a good OBD2 scanner that can read module-based DTC's and see what the modules are spitting out for DTC's. SInce the warning comes on right as you turn the car on, it's likely a hard fault. One of the related modules will have a DTC set...

    Question about Main Screen when using any of the map options

    Mine does that once in a while. It zooms in when on city streets and have a turn coming up and then resets when I take it. Doesn’t do it a lot. There’s one right turn near my house that it always does it at. doesn’t do it on highway or anything like that. Pretty sure it’s a Waze thing as I...

    Smoking on startup after sitting

    Unfortunately, i don't think that's the case. It's been sub-10 degrees in the AM where I am (except today for once) and my startup looks nothing like that. I get a whispy white smoke that looks a lot thinner and dissipates. ANy codes by any chance? CEL on?

    Rear differential brace

    I think it all depends on which brace one uses. There are many designs now. Some like the steeda brace support both sides, so there would likely be very little torsional force due to asymmetric support. And then there are some of the older "classic" designs that brace on one side and might...

    Rear differential brace

    Agree, the bolt alone isn't the end-all cure for the issue. A class 12.9 is only about ~15% stronger than a 10.9 bolt, but one downside is that it is more brittle. SO while the Ford OE bolt may bend as it approaches failure, the 12.9 bolt will resist this much better, but then just snap when...

    Smoking on startup after sitting

    If its valve seals, you can pull a plug to inspect and usually they will be a bit oily/carboned up a tad if the oil is leaking into the cylinder and burning off. You say it's mostly from one bank? I forget how the exhaust routes on those 5th gens Is it 2 into 1 into 2 or is it 2 pipes all...

    Smoking on startup after sitting

    You said the oil level was high. When you drained the oil, was it only oil or was there any sign of coolant? That generation Explorer was plagued with an internal water pump that is notorious for leaking. When the leak gets bad enough, it may actually leak coolant into the oil pan. If you...

    Rear differential brace

    Kind tempted to check mine, but I also don't want witness marks on the bolt in case there is an issue. I also think if i go through the trouble of removing the bolt to check it, i might as well install a brand new one.

    Rear differential brace

    I’ve found by way of past experience that the dealer holds the cards here and if they want to claim some BS vaguely related reason to not cover you, your recourse is to challenge it by way of legal action. Not always cost effective depending on the repair. This is why it can be helpful to...

    Rear differential brace

    It depends on the dealer. Some are mod friendly, and some are not. I'd say as far as my local dealers are concerned, they are not mod friendly based on past experience with my Mustangs. I'd probably pull it off if i had to drop it off for anything.

    rumbling noise when switching to SPORT MODE

    Mine does it too. I've heard others say this as well. Forget who explained it, but they stated it was something in the transmission that resonates in the bellhousing. It changes depending on the modes and is loudest in Sport. Stated this was normal. That's a 3rd hand explanation i know...

    removing 2nd row seats

    That’s what I ended up doing for the middle bench. Hated routing the harness in/out so I ended up buying a new buckle ($35 or so) and digging a harness out of a junkyard vehicle one of these nights I’ll cut it all up to make a sort of jumper I can just plug into the middle seat plug when I...

    Trade in with tune

    I’d return to stock, or closer to stock. Most dealers look down on tuned cars or aftermarket mods because it reduces the size of the buying pool. I know when I was shopping for an ST, I avoided any vehicle that wasn’t 100% stock. The only issue I see with returning a car to stock and not...
