...hey guys needs some help not a major issue but my car when warm at idle fluctuates between 500 rpm to 1000rpm. It’s never steady unless the car is cold wtf?? I’m trying to figure out what sensor it could be. The car also idles low about 475rpm to 500rpm, when I come to a stop. I could use some insight

check your MAF sensor. it might be dirty. clean it out with carb cleaner and see if that helps.

Yeah it could be..... it could also be the EGR system. Try pulling apart the IACV first and cleaning it thoroughly and see what happens. Also replace the gasket when you pull it.

You could also have a vacumm leak somewhere in the system. Those are always fun to figure out.

Fuel Filter. My car did that before I changed it.

When was the last time you did something as simple as a tuneup?
