Need help - Power loss at higher speeds
 

Hello all!

Love my 2009 Hyundai Accent. Today on a long trip I began to loose power at higher speed (between 125 and 145 KMH). It would just konk out and loose power. Once I pulled over I gunned it and it was fine- this happened a few times, and the last one I noticed it was getting SOME gas but barely any then it popped and was fine. I am thinking along the lines of fuel filter maybe...

It is not doing it now, and I planned to take it into the shop but I am kinda broke. Of note is also the fact that I filled it with supreme before this trip (I don't use it normally) but my mechanic didn't think this was the issue.

So no ideas here?

Yeah, no ideas ... lol

It could be many things
Weak fuel pump
Clogged fuel filter
Junk in the gas tank
Faulty injectors

The thing I would do first is throw a couple of bottles of injector cleaner
And hope for the best
If it comes back then got to start with monitoring systems while at speed
And find out what isn't working right
Not easy without the proper equipment
