Looks like you are in the rich mode?..number things can cause this..plugged air filter,leaky injectors/bigger injectors(non-stock),non-accurate coolant temp. sensor,a cat.convertor thats not doing its job,a stuck open thermostat or non-existant one can cause this,a weak fuel pressure regulator?..do some checking and post what you find..good luck
