Answer
Hello, find a mechanic that is willing to work with you on this and try to diagnose it correctly without putting expensive part on and hoping it will get fixed.
Have it checked for diagnostic trouble codes which may be stored in the computer.

there may be a restriction in the exhaust system, possibly a catalytic converter that is partially clogged. This can be checked with a vacuum gauge connected to the intake manifold
It may have a bad airflow meter
The coolant temperature sensor for the computer may be bad.
