Maybe a plugged hose or something? Please if you have any info, i would greatly appreciate the input.

Make sure the vacuum lines to the EGR MODULATOR are not plugged or dirty and clean the throttlebody where they attach and then replace the modulator, they always (99%) are bad.
There is also a MAP sensor that reads the engine data and may be improperly reading, make sure the vacuum line to it is clean an the filter it attaches to is allowing enough vacuum thru.
