Weird Gas Gauge/Fill-Up Issue

[mannings]

I purchased my 2013 Sonic earlier this year. Had no issues until I went to fill it up for the first time.

I did fill it up a little (though not much) past the full click (used to doing this on my Ford with no issue). Stopped doing this after the first time.

Anyways, after this I had two big issues which I am unsure if they are related.

My gas gauge no longer reads correctly. It always displays 2 or 3 bars and 60-90 miles to empty.

The other issue is sometimes after filling up with gas, I will go to pull out of the station and as soon as I hit 10 MPH, the engine stutters and stalls (only happens about half the time). I then have to rev it for a minute or two until it stops. Then it is fine until I have to fill up again.

Have had it checked out by 2 mechanics (not a Chevy dealer though) who have looked at the Tank, Solenoid/Cannister, Sensor, Electrical etc and have found absolutely no issues.

Does anyone have any ideas or experience similar?

Had same problem kinda

I did this with the fuel once or twice. Never had an issue with gas gauge but engine did start to stutter. I would start with a code reader and look for pending codes if engine light isn’t on. More than likely you will need to change your PCV valve. I believe I got mine from O’Reilleys or amazon and it cost about $30. If you have basic car skills you can do it yourself. Otherwise use the internet. Disconnect battery before replacing. It should take about 15 minutes tops. Leave battery disconnected for about an hour to reset computer once done. This may help fuel level problem also. Seems like you pushed the Fuel level float and got it stuck. I don’t know. Hopefully this helps. I know some great YT channels and repair guides if you need help but simply googling the problems helps a lot. Good luck. I got 2013 LTZ 1.4 turbo.
