For the last year or so I've noticed the occasional odd behaviour and noise from my 2020 Expedition.
Our street is on a slight hill, and the Expedition is parked facing uphill. When I start it cold, and then pull away without waiting, when the engine gets to about 2000 rpm it feels like it's holding back, and there's a faint "pew pew pew" noise from the engine.
If instead I wait for the engine to warm a bit, or if I gently rev the engine a little first, then pull away, it doesn't exhibit this behaviour.
I don't have the cam phaser rattle noise so I don't think it's that. Just wondering if anyone has any ideas. It's due in for a service in a couple of weeks so I might bring it up then, plus it's under the extended warranty still.
