How long since a tune-up? Any applicable mil codes? Sounds like you may need to replace cat--muffler and exhaust. Believe me, I understand money issues. Have the same problem myself. I can't reccommend anything that isn't a factory set-up. 02 sensors are part of a tune-up. What is engine litre size?
You can check mil codes, yourself.
