Sounds like a solenoid fluttering to me ;) but, if its there at cold start, you can’t hear it over all the other cacophony until it warms fully up and goes into “quiet” mode… i think thats why i’ve never noticed it before… it was sitting at a gas station after driving it and i was putting...

Here’s mine doing the same red thing.. the ford media person who monitors the forum just messaged me about it

Did you ever figure this out??? Mines doing the same thing!!!!!

I’m not counting that out.. but this really seems like an electronic buzz rather than a loose rattle… NOW…. if the waste gate is s stepper motor and the loose linkage is causing the motor to buzz cause it can’t find its location point…. That… i can see

I’ve honestly never opened the hood on my 2.7 bronco with the engine running before…. Heard this “fly in a kazoo” intermittent buzzing while the engine was idling… Kinda sounds like the Idle Air control valve on my rx-7. Something tells me it’s normal operation.. but.. never heard that...

Sooooooo THATS what that button is and does…. I’ll chevk that out when I wrestle the bronco back from the wife

The overhead light on the rear rollbar will not shut off if my kid leaves it on when i turn the car off!!! I opened the door, pushed the button, shut the door, all the other lights go out but that one…. Tried that several times, light stays on. the only way to get it to turn off is to GET IN...

Its not lag… I know what that is.. Its not building boost at all during acceleration from a standing stop.

Having an issue in my 2.7…..maybe…. (3,500 miles) my wife usually drives the bronco…so I only get in it once a week. something seems weird.. When you start from a standing start, and accelerate moderately, it seems like its about to fly apart, winds out, makes a lot of engine whining...

Im betting that if you post a vid of starting up your Bronco with the phone in front of the car, we’ll be like, “yep”. my wife doesn’t notice anything either…she knows cars.. she just isn’t as OCD as I am, nor is she as anxiety ridden, nor as micro detail oriented! she’s like.. “MEH…. It...

Yeah, i’ve noticed some hiccups under light acceleration when just starting out, if i was tuning my harley or an RX-7… i’d say it feels like surging because of a lean condition and would be looking at my Wideband O2 data log for 15 and up blips…. BUT… this is a new car under warranty…. Sooooooo...

Yeah…. The 4cyl was definitely smoother in the revs, but it felt “springy” and not solid feeling and sounded more “sewing machine” like vs “Tractor-like” of the 6 cyl! I’ve combed through youtube.. they all (stock anyway) sound like just like mine. (Unless they are showing a known problem of...

Yeah…. This thing is NOT what I’m I JUST found out about the cam phaser noise…. Its definitely not doing THAT yet!! (funny… the pentastar in the pacifica has been rattling just like that (maybe a bit quieter) for two seconds on startup for 100K miles.. and they consider it completely normal!!!!)

First.. background on me…. I’ve built a few v-8 engines for street and drag… tuned tubo rotaries in RX-7s and two carbureted 360 swaps into jeeps…. So.. this isn’t my first rodeo!!!!! ANYWAY… Just got our Bronco last week, black diamond 4 door with steelies and the 32”all terrain tires, I...

We’ve been looking at Broncos since they came out, finally found one that fit our wants/needs/budget fairly well last week! (We HAD found a similar one (almost exactly) a few weeks prior, but after test driving, the dealer told us that there was a $7500 upcharge over the sticker just because...
