This phase I trial studies the side effects, best way to give, and best doses of tanespimycin with or without gemcitabine hydrochloride and cisplatin in treating patients with advanced solid tumors. Drugs used in chemotherapy, such as tanespimycin, gemcitabine hydrochloride, and cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Using more than one drug (combination chemotherapy) may kill more tumor cells.
