scan for codes even if the light ain't on , may be the catalytic is clogged , have someone hit the gas and see if there's a healthy blast from the exhaust .let us know what happens

then you may have an injector stuck open , you should get a fuel pressure gauge and see if it's right , shot in the dark you can replace the fuel pressure regulator if the injectors are good , clean the AIC port but first you should scan for codes
