The vehicle listed above has a 1.6. It is losing power at 2,000 RPMs; it also sounds rough. I have changed the oil and filter. Changed air filter and replaced plugs. It is a little better but still lacks power and sounds rough.

Hello,

There could be a number of reasons why you are losing power.
It could be due to a weak fuel pump, worn out mass air flow sensor, plugged catalytic converter, clogged fuel filter, jumped timing belt.

Here is a helpful guide that goes over the typical reasons:

The best course of action would be to take a look at each individual component and take appropriate action.

Cleaning out the mass air flow sensor can improve drivability.

Go through this list and let me know what you find.

Thank you.
