Why is my Kia Sorento's engine revving while in idle?

I've noticed that while my Kia Sorento is in idle, the engine seems to rev up and down sporadically. Is this normal or should I be worried?

Hi Catherine, it's not uncommon for the engine to rev up and down slightly while in idle. However, if you feel like it's excessive or the car is vibrating abnormally, it may be a sign of an issue. I would recommend taking your Sorento to a mechanic for a diagnostic check to ensure everything is running smoothly.

Hi Catherine, this could potentially be a sign of a clogged air filter which can cause the engine to rev up. I suggest checking your air filter and if it's dirty, replacing it. This is a relatively easy and inexpensive fix.

Hey Catherine, I had a similar issue with my own Sorento and it turned out to be a faulty idle control valve. This is a common problem in these models and may need to be replaced. I suggest taking it to a mechanic for a proper diagnosis.
