I own a 01 Hyundai Sonata 2.4L and the error codes I get after an ODB check is p0171.
When i first start it up it's like it loses power, constantly hiccuping. So i have to press on the gas to keep it on. But eventually it goes back to normal when I drive across town it runs smoothly every now and then.
It says something about system 1 bank 2 lean or something. And it brings up a list of what the possible causes are, like a air leak, or fuel injector.
I wanted to know if anyone on here had the same problem as me, and would know what you really think it could be. Because from what the car does, it's like it loses power or pressure or something.
