    The Truth about ethanol: Big oil is lying.

    Ethanol was added to gas for two reasons. It boosted octane after, MTBE(methyl tert butyl ether)was removed from gasoline in 2005(ground water pollution). However the recent government 'mandate', that requires all gas to be blended, began a couple of years age. Corn producers, have greatly...

    The Throttle Position sensor, is tied into the transmission. There may be a relearn procedure for the TPS and transmission module. Check all your connections, near the throttle. Good luck.

    best replacement caliper -oem

    I was told years ago, to avoid 'rebuilt'. I had a reman pop a seal and another sticking/dragging. New OEM are super expensive($150+). Replacing one caliper can cause brake pull issues, so replacing in pairs can be pricey. Many are made in China. Replacing with a factory OEM used, sounds crazy...

    Easiest way to switch my 20” rims for 18” rims?

    Your vehicle has tpms, with sensors in each wheel. You will need a tpms reset tool, to change the wheels. I changed wheels on a 2009 Lincoln MKZ. The chrome wheels, were part of a $2,700 'option' package. I found wheels, that had no sensors($150). I had to buy bands and sensors, plus the reset...

    Please someone help me - bypass the amp

    No amp in some models. The sub woofer does have it's own amp. The JBL system may. The base cassette radio do not. Go to your local junk yard and get the correct plug off the harness. Splice it in and use an install kit wiring adapter. They are on Ebay for $5.

    Maintenance Advice

    Never buy a vehicle owned by female. They usually don't give a rip about maintenance. When something breaks, they go into a panic. I have niece, sister and cousin all with same attitude. The know nothing about cars and don't care. My cousin has had car after car, with problems. She now leased a...

    600 miles enough for break in?

    Rent a car for the long trip. I always do. Leave the new one in the garage. I had a 18 wheeler, throw up a rock and ding the hood of my last rental. Hertz has $9/day damage insurance. It was covered. Imagine that was your brand new ,500mi vehicle? In 2013, the car in the next lane, hit a deer...

    2016 85k miles, transmission went out

    I own a 2011 Mustang GT, with a 6r80. The battery suddenly died and flat wouldn't start. I boosted it and it started. The transmission would not shift past 2nd and was banging gears hard. The car had only 3,100mi. I installed the new battery and it drove perfect. I can verify it shifts firm...

    2017 EL Limited- Rust?

    Ford has had this problem for years, with aluminum tailgates. Get to the dealer and show them. It should be under 5yr corrosion warranty.

    Expedition - Impressed (tow capacity)

    Just because you can tow on flat land, doesn't mean it's safe or legal. You can hook up a small UTV and move a trailer around. Loaded with passengers and cargo, you are overloaded and unsafe. The rear end 'sagging', is a clear indicator something is wrong. Towing at the 'max' will shorten the...

    How would you easily access it. It would be almost a foot away and out of reach?

    Front planetary graneded. You should have L1 or reverse, if it was something else.

    2016 85k miles, transmission went out

    I never heard if an input rod failure. Get a second opinion. The 6R80 goes nuts after a dead battery. Was there a battery problem recently?

    Train Horn on the Expedition!

    That sounds like UP, BNSF or old Conrail horns. Every railroad has there own tone. Locomotive air compressors function in the 125-140psi range. A min of 90psi, for the brakes to work. The horns are designed for that air pressure.

    AC filter for Expedition 2015

    The Expedition's engine sits partially, below the cowl. The cabin filter is usually under the cowl cover. I believe because of this design, there is no cabin filters.

    Design Miscue

    Its not a true dual. It's 2 to one, then 1 back to 2. Dead weight. In some cases a single exhaust, makes more torque.

    Timing Chain Cover Leaking - 2007 Navigator

    A blocked exhaust, will cause excess crankcase pressure. It may cause leaks around valve covers and main seals. Any chance you have a clogged CAT?

    Timing Chain Cover Leaking - 2007 Navigator

    Tighten up on the bolts. That area only gets oil splash. It may be leaking somewhere else.

    Tune Question - Limited vs Platinum

    I just read on a Mustang forum, Ford is flat, denying warranty on any 'modified vehicle'. If Ford engineers thought the 3.5l was capable of more power and be trouble free, you bet they come that way. I doubt the transmissions or single exhaust are capable of handling 600hp. The drive train is...

    Toyota uses a nice, factory black coating, for rust protection. Does anyone know what it is?

    Rented Max Limited

    The Expedition, was the Bronco replacement. They sold so many, it cut into F-150 and Windstar sales. Ford slow rolled upgrades and new models. They want to sell high profit, F-150 trucks and claim #1 in sales for 25yrs running.

    Rented Max Limited

    Wrong. It was the 4-door Bronco. Something buyers wanted.
