Personally, I would do a spring clean on the throttle body, MAF and rip out any sensor on the engine that you can get to... Clean them thoroughly with petroleum or meths, this should be your first "Cheap" option.
If the errors are still their afterwards then at least you may have peace of mind the the components are good to go !!!

BTW, has it been serviced recently?

Welcome to the Werkz.

Check for vacuum leaks on the intake manifold & cracks in the intake ducting between the air filter box and the throttle body.

For it to be rough, its a chamber firing issue...
Coils, plugs, fuel/air mix, MAF, Throttle body etc...
It could be one, or a combination !!
Sorry I cannot be more help at this stage but I will be "On It" as soon as poss...
