WTF?

Misspelling brought to you by tapatalk

It may be that the flux capacitor is wired with reverse polarity creating a phase shift thus causing the issue your experiencing.

 

[toms89]

Seriously though.... not sure if this is a question or not. A little more detail may help others to diagnose if it is.

Your expedition has an ignition miss or is stumbling at low rpms??

Vacuum leak, spark plug bad or excessive gap, bad coil, water in plug well are a few common items to check.

I think the truck is just having a bad day.

Broken vacuum elbow at the back of the throttle body or bad iac motor.

Specifically during acceleration at low revs it chokes, at higher speeds it is OK

 

[IMINYOURCHAIR]

could you let us know what you are defining as "chokes" ??

 

[bodzio]

It's about lack of power.
Forgive my poor English

Can you read any codes from the check engine light? Where are you from?

Also how many miles/km's on the vehicle? Could just be time for new spark plugs like Tom said.

Poland, according to his profile.


Codes would definately help, but best to start with the basics; plugs, wires, vaccuum leaks, etc...

Oh I see it now. Sorry still learning about how to use tapatalk.

I am not sure what you have for car parts stores in Poland but give them a phone call and see if they have a code reader you can use.

Problem solved, wine turned out to be plug, it probably was a tributary of the control of air to the engine .


Many thanks for your help
