Van was running great one day. Went to work and eight and half hours later came out and it would not start. We assumed the battery was the issue and bought a new one. Still would not start. Had it towed to the house. Use a code reader to find out the MAP sensor was bad, and replaced that. Now it will run but it is rough. And throwing the Ow sensor code. So having that replaced now too. Should this fix my car, or is there an underlying issue that I will have to fix?

A bad O2 sensor can make them run rough as will a bad MAP sensor. Check the wiring to both for a short. Especially the o at sensor wiring. They have a bad habit of shorting on the rear of the engine.
