    Turbo Boost causes CB buzz

    The first question(s) should be at what frequency is the noise being generated: Is it being received at the RF receive frequency (~27.00 MHz) or is it being heard at an audio frequency (20 Hz - 18,000 Hz). To determine that, disconnect the antenna. Is the noise still prevalent? If it's gone then...

    Buying Wiper Blades

    Nope. Not if you're looking for a rear wiper blade for a 2017 Expedition.

    FORScan is not a "scanner". It's a computer program. It would probably behoove you to spend some time perusing the MANY entries regarding its use right here on this forum.

    No sir, and I don't plan on it. I'm too old to worry about my "tranny".....there are a lot of other things I'd like to "tune" and that ain't one of them... :-)

    2011 Expedition Limited - Enabling/Disabling Features

    07navi said: ↑ My warning comes on every time I go up on the mountain here. I went through 50 +- cars without it and think it's a bad idea. Have you thought about changing the low pressure limit in Forscan? The other suggestion would be to raise your overall tire pressure a psi or two....I...

    Catalytic Converter issue or something deeper?

    I'm not a mechanic and I'm a total neophyte to Forscan but the first thing I would do is check ALL the plugs to be sure they weren't loose in the hole. Secondly I would check with your "code reader" again to be sure there weren't some other cylinders misfiring and if that didn't prove out I'd...

    I presume you have already downloaded and installed Forscan?

    It will definitely allow you to change parameters but exactly which parameters would depend on the make, model and year of your vehicle. You would undoubtedly have to dig around on both sites to determine whether others have discovered the correct parameters to change for your particular vehicle.

    I grabbed this OBDII from Amazon: https://www.amazon.com/gp/product/B08G4MQCR9 For actual programming I use a laptop and the above hardwired OBDII but there is no reason you couldn't use a desktop if you want to drag it out close to the vehicle and plug it in. I have also used my laptop on...

    This one will probably work just fine. The only drawback is you have to physically change the switch setting when using it and that's a pita. See my note to Sticker....

    There is no reason at all to "upgrade" to paid version....after the 2 month trial just renew for another 2 months. As of now you can do that indefinitely. As far as the interface device goes I just use one that has automatic switching between HS and MS modes...I think I paid around $20.00 for it...

    During the last three weeks I joined Expedition Forum, which I will be eternally grateful, and during this time I inquired about a couple of situations I had with my Expedition. Several members responded with their thoughts and ideas about how to deal with my situations on my Expy. I eventually...

    Help Lost key fob while driving

    The "smart key" fob is two things: it's a transmitter that sends an encrypted signal to the vehicle at 315 MHz (in North America) and it is also a passive transponder that replies to an RFID signal emitted from the vehicle at 125 KHz. If you happen to have a portable radio receiver that will...

    Weird behavior with E85.

    From the 2017 Expedition Quick Reference Guide: Use only UNLEADED gasoline blended with a maximum of 15% ethanol and a minimum of an 87 octane rating. Do not use E85 (ethanol), diesel, fuel-methanol, leaded fuel or any other fuel because it could damage or impair the emission control system

    Acquiring signal...

    I would be more apt to believe that it was your cell phone interfering with the SiriusXM. SiriusXM transmits in a 12 MHz segment between 2.32 GHz and 2.3325 GHZ. Your cell phone's wireless and Blue Tooth transmit around 2.4 GHz. Depending on the carrier you use (Sprint, AT&T, Verizon, etc..) the...

    Liftgate Ajar

    This is to ALL of you who have responded to my query: After owning this vehicle for a few years, and after you have informed me that the rear glass window on the lift gate does indeed open and where the button was to open it, I went outside, located the button and lo and behold! The glass...

    Liftgate Ajar

    Great idea! Now what is the procedure for doing that? Is the alarm triggered by the sensing of an open circuit to the sensor or is it triggered by the sensing of a closed circuit?

    Liftgate Ajar

    I should have been more explicit. The 2017 Expy EL doesn't have "flip-up windows". And all the doors, including the rear lift gate are verified closed. As I indicated; I'm pretty sure it's one of the rear lift gate sensors - there are two - is defective. My question is: what is the procedure for...

    Liftgate Ajar

    I have a 2017 Expedition Limited EL that is showing a Liftgate Ajar warning on the dash. The interior lights stay on and the rear view camera guide lines are not showing when in reverse. I suspect that one of the two liftgate sensors has gone bad. My question is: What is the procedure for...
