Multiple codes Part fixes not working

[Bluebunny74]

Hi Sonic people,

I have a 2015 Sonic LTZ 1.4 Turbo that has 119,000 miles on it. I got these codes on Friday

P1101
P0171
P0106

I bought the MAF Sensor and installed it. Didn't fix the issue. I checked the filter and it is fine. I ran codes again

P0131
P0030
P0036

I replaced the O2 sensor. It is still rough idle and the cooling fan stays on after I turn off the car. We cleared the codes and read that to reset the system after installing the O2 Sensor it had to be driven two times up to 10-15 minutes. I drove all the way to work no light, but when I went to lunch it came on. Now it is giving these codes

I can't afford a mechanic shop and I am getting tired of buying parts with no fix. My friend thinks it might be the coil pack like a spark plug not firing.

Any ideas?

If I'm remembering right, you're dealing with the PCV system. Valve Cover and Intake Manifold should do you, if you haven't already replaced them. Valve cover is super easy, intake is a little more annoying.

I replaced the valve cover. Now I'm getting P2261 and p0420
