I've put the car on jack stands and in neutral. All wheels rotated freely.
Here is what I can recall doing so far:
wheels checked for free rotation.
air filter replaced.
MAF cleaned (no change) then replaced.
tire pressure checked multiple times by myself and once by a shop.
AF & o2 sensor replaced with Bosch units (no change in mpg or performance) and then originals re-installed.
Potential culprits left:
the tires (milestars) are not old, but one or more of them have a flat spot creating a very noisy ride, especially above 45 mph. I've put tires on a civic that were supposed to help fuel economy and maybe noticed a 1-2 mpg improvement, but can't say for certain. I've never had a set of tires cause poor mpg to my knowledge so I'm not sure replacing these would change anything.
I read in from another source that the honeycomb material in a CAT can break free clogging the exhaust and hurting performance/mpg. I haven't driven another 2.5l camry to compare, but acceleration seems good to me so I don't think there is anything clogging the exhaust system. I have no idea how I'd check for this beyond replacing the CAT, which would be terribly expensive and really a shot in the dark.
faulty fuel pressure regulator: i've read that these can go bad and allow too much fuel to pass by hurting mpg.
I'm confident that it is not my driving habits causing the poor fuel economy. Not sure if I mentioned this, but I contacted the prior owner who used the car for commuting. They said they would get 28mpg on average (mixed driving).
As someone above mentioned, I think I'll learn to use the scan tool more thoroughly and see if some additional data can lead me to a solution.
Just like the title says....just about every other Camry generation has one of these threads, so it's only fitting for Gen 7 to have one, too, especially now that they're out on the road finally! :chug:
Post away, but please keep it on topic!
From when I bought a used 2016 Camry SE - two years ago - until today, the center console lights will occasionally flicker for about 15-20 seconds after removing the keys from the ignition. Any explanation?
Additionally I'm having the radiator replaced tomorrow, due to a...

I have platinum warranty and it is 35550 miles. it is a 2015 SE Camry. I've noticed in the last several months when I turn off ym engine, and right before I take the keys out of my ignition there will be a flashing and flickering light in the center...
