Help! Why is my engine doing this?

Started my 2019 with less than 40k miles this morning and the engine is surging like crazy...undrivable. Any ideas?

Upload video on the youtube and drop link here.

What you mean surging? any weird sounds ? vibration or? dont drive it if you think something is wrong, just take short video

 

Bad gas or fuel pump?

 

Edited....uploaded to YouTube. When I put it in drive it's doing the same thing....surging like I'm pressing the gas pedal over and over.

 

Holy crap. WTF.

 

Idk, subbed to find out

 

Does it stumble or clear up as you get on the gas in neutral?

If you had doe plugs or anything under the hood recently a culprit could be a vacuum hose thats been left off or knocked off by accident.

 

What happens when the engine is warm?

 

That's weird, but it doesn't seem like it is going to blow itself up. If you give it some more gas and hold it steady above 1500 RPM, does it still surge up and down? Hopefully it will set a code if you let it run long enough.

Seems like maybe bad gas, or maybe a vacuum line somewhere popped loose or cracked?

 

Throttle position sensor?

 

It sounds like its trying to get fuel but its not pumping? or something like that. I feel like ignition is not happening in the engine, now hood is closed so we can't hear that well but it sounds like that to me. Some others are more experienced here so lets wait and see what most will say

 

It could be the IAC sensor, just a guess hopefully it will throw a code.

 

Are you smelling gas in the engine bay?

There is a fuel pump recall. Your 2019 is covered for 10 years regardless of mileage.

Try to rev it up while in neutral while it’s surging and see if it will rev up or not.

 

It's almost behaving like an carbureted engine with a sticky float valve. Very strange.

 

Was out letting it run and now the idle is better but trac off and check engine light is on. Gas pedal was slow to respond but revved it up to 2k ram and held it a bit and now it smoothed out at idle.

 

Air filter clean? Pull it out and see if that stops if not move on to next suggestion

 

If you can get the trouble codes read, let us know the codes.

 

Try OBD, see if its reading any codes, dont drive the car
