Default burns to much gas

got 4.0 burns to much gas and it a standard rwd. Threw codes for egr sensor and 02 sensor. i know that it shouldnt be both of them and only one of these may be the culprit. my check engine light is on and i figure only one is he cause and the other is just an effect. what do you think.

You need to find out what bank the faulty 02 sensor is. If it is a precat sensor, this will make your truck run rich; if it is a downstream sensor, then this isn't your problem.
