2010 Subaru impreza

Hello everyone!

I am at my wits end!. My car has become sluggish (feels heavy) with poor acceleration and poor fuel consumption. These are the things I have done already and nothing has worked:

Timing belt changed
o2 sensors changed
Fuel filter changed
Fuel injectors checked
I have been told my cat converter is damaged, but I unhooked the exhaust at the engine and the symptoms were still identical.

The only thing left I can think of is the MAP sensor may be damaged.

Please help! I can’t afford to get cat converter replaced if that doesn’t fix my issue.
