Welcome to 2CarPros.

Is the check engine light on and staying on or flashing when the engine is running?

If it stays on, has the computer been scanned to retrieve diagnostic trouble codes?

Has the fuel pressure been tested or has anyone checked for a partial plugging of the catalytic converter? If not, have that done.

If there are no codes, then it becomes a test procedure. Have you checked fuel pressure? Have you checked to see if anything is plugging the catalytic converter?

Let me know.

Have you tried removing a pre catalytic converter oxygen sensor to see if it changes? The exhaust may appear to be good, but internally, there could be issues.
