Hey wise peeps - advice?
I have a 2008 Mountaineer AWD V8.
Today - the car died in the neighborhood when my wife was driving home (she coasted into the driveway) She was probably idling, or close to idle - she didn't even realize the engine died - she thought it was a power steering problem - lol).
The car restarted with a slight clatter (valvetrain - I thought, but only a second or so, right at startup) & died a second time.
Then, restarted normally & ran fine (idling in the driveway).
An hour later, I took the car on a test drive around the neighborhood - no issues - it seems fine.
When the car died - it did not throw a code (I checked with my scanner) and after test - still no code.
Key Facts:
108k miles.
I replaced the fuel pump and filter with Motorcraft parts - last summer I believe (fairly recent - probably less than 10k miles since that)
Oil is synthetic, and looks fine.
Coolant is fine (full) vehicle is running at normal operating temp.
I replaced the water pump (also MotorCraft) very recently, because the o-ring failed -- it was leaking - I probably could have just replaced the o-ring, but I replaced the entire WP, belt, and t-stat (I put a high-flow 170 degree t-stat in it because they were on sale at RockAuto, and its friggin hot in Houston most of the time). The operating temp did drop a bit on the gauge - FYI, So the coolant is new, as well.
The spark plugs and coils are original & have never been touched, I could replace those, but I suspect an issue with either a coil or a plug would throw a code.
Everything seems fine -- The only thing I could think of is that the air filter is dirty, but I don't really think that would kill the motor.
Also, I have an extra fuel filter (somehow I accidentally bought 2), so I thought about changing that again, just to be sure that wasn't an issue.
Any suggestions? My wife is afraid to drive it & wants to drive my Lightning to pick the kids up - and that scares me,,, LOL
