p0303- cylinder 3 misfire
p1443- evap canister or purge valve or relay
p0171- fuel inj sys too lean bank 1
can you get under car safely? follow fuel line starting at tank, to filter, then up towards motor and look for physical leaks?
i dont know what/how to check evap canister, but whenever i want to do something, i google and then youtube to see if there's any info out there about it.
do you have an obd scanner, or autozone/advance place nearby... if you can, maybe clear the codes, run again till light appears, and re-read to make sure this is all you are getting. let me know if need more help-
