Have you checked it for vacuum leaks? Make sure you check the TBI to intake mounting flange gasket as well. Check the vacuum line that's going to the map sensor, make sure it's pulling vacuum as TBI engines were bad about gumming up the throttle body so bad with carbon it would plug the vacuum ports. Also what shape is the tune up in? When was the last time it was tuned up?
