2011 focus

[Lindsey]

Okay y'all. Car is choking on start up and in reverse until I get to driving. About 1500 rpms it shutters real bad until I get to 2000 rpms then it drives fine. It's also sucking gas bad. It's been to five shops and nobody can figure it out. I'm going broke bc of this car.
Changed
Throttle body
Valve covers
Spark plugs
Air filter
Battery
Maf sensor and connector
Egr valve
All tests coming back good no check engine light on.
Idk what else to do. Has anybody had this issue?

What about the o2 sensors? There are two of them on the Focus

Like Tom said , how old is your front o2 , only the front one will make it run bad

Looks like you covered the ignition side. Any of these signs? kind of sounds like the engine is having trouble breathing? How many miles do you have?

No check engine light on at all for anything. And the bucking is just in between 1k and 2k rpms then stops. Idk if maf sensor isn't picking up or what

They said it's my computer. But after 1200 spent idk how it could be when it's only jerking in between 1000 and 2000 and when I back up. I don't get how this randomly happened.
