WOW, that's a lot of codes. First thing what I would do is remove the air intake hose and look at the throttle body assembly and see if it is full of carbon. If it is. clean it up real good, purchase some Throttle body cleaner and spray away. The P0101 is a MAF sensor, I suspect that is dirty too, purchase some CNC MAF cleaner, and spray the filaments Do a search on how to clean properly. Then put everything back together, disconnect the negative battery cable for 15mins and reattch or use the scan tool if you still have it and clear the codes and drive. If the CEL comes back on, check the codes again, if they are the same, i would replace the throttle body assembly, and go from there.

Obviously the person asking the question has very, very limited knowledge and the first thing I would NOT do is anything Tom suggested ... Take it to a qualified mechanic! Period, paragraph, end of subject!

"Take it to a qualified mechanic" is not the point of forums.
