sometime the tbi throttle shafts wear and cause vacuum leaks

also have you checked the tps.. ? hows the spray pattern out the injectors

egr could be acting up..

just because a sensor was replaced don't mean it can't be failing

check for vacuum leaks, cracked hoses /etc
play in the tbi throttle shaft..

smooth signal from the tps. as it travels from open to closed
