try some choke cleaner on tpas switch and around tbi unit it may be the tps switch it self. For the map sensor check to make sure hose leading to it isn't soft and sucking together or has a hole in it etc. Otherwise a pro will have to check it for a short. of course you can try to replace these as well as they may be bad.
