So my car went into reduced engine mode on the highway. I turned it off and it wouldn’t come back on, so I jumped it, it came back on but now, so I turned it to give it time because this has happened before. But when I tried start it again it wouldn’t start at all so now it’s cranking but wont start up.

It sounds like the throttle body needs to be serviced or replaced. I would run the codes to help confirm the issue which this guide can help with:

also, this guide can help explain the reduced power limp mode problems and how to fix them:

Here is how to remove the throttle body in case a code comes up for it. Also, you may be able to clean it and have that fit it.

Remember to clear the codes once the repair job is completed. Check out the images (below). Please upload pictures or videos in your response of any problems so we can see what to help you with.
