I just bought a 2016 chevy sonic auto 1.8 L 108,000 miles private party and I'm getting codes for maf sensor, iat sensor (P0113), system too lean bank 1 (P0171), EVAP system (P0496), Barometric sensor (P2228), and a no description code for (P00F4). I replaced the maf sensor but the others are still there. I know this car is crap but I got it for a good price. I noticed a recall on these cars for the purge valve. My question is are these codes in relation to the purge valve? Will they be fixed by just fixing the purge valve and if not which one is most important to fix cause the car is stalling during start and sometimes doesn't start for some time. I really just want to get it to run better to resell it. It also has lots of vibration when idling when sitting in the car compared to standing outside the car. I've watched lots of your videos and I am so glad your passing on your knowledge to me cause I go through lots of cars so thank you!

That many codes. I would assume that thing might have been flooded out or in a wreck and the wiring is damage. Even evap system is complex. It's run by computers. You need a guy like me to test it with this high level scan tool. I would advise at least paying a guy like me to analyze it to tell you whether he thinks the whole system is screwed up or that there are various separate problems
