Its the catlytic converter, but if you'ave already checked the exaust then it's not that. Check your crank and cam sensors for resistance one of them may be bad and not setting a code. We have no information for these cars, but check for the kock sensor giving excessive retard and check iginiton system for proper operation. Also check the map sensor for proper operation. If that has a vacuum line going to it see if it's sucking together or soft. If it's soft then replace the vacuum line. And check the gasket around the map if it goes directly to the intake.
