Default Loss of Power

Recently my stock stang started gradually loosing power upon acceleration. I can have the gas peddle almost to the floor and it seems as though the engine takes forever to catch up. I have replaced plugs and gas filter and neither fixed problem. I thought it might be the catalytic converters. Any insight on my problem?

Is your engine revving with no power or is it not revving as well? stick or auto? The more info you can put out the better someone can help you.

clogged cats can cause this, but USUALLY theres a CEL code being thrown. is your car popping codes? (service engine soon/check engine light)

my car just had a fuel pump go out. it would drive normally under half throttle, but if i tried to floor it the car would literally go limp and start bucking, then catch up a bit, then fall back on its face. could barely rev it in neutral either.

No service engine soon lights....no warnings on dash. It doesn't spit or sputter like a fuel issue. It is like going slow with your foot all the way down on the accelerator. Unresponsive.
