1995 2.2 ext cab 5spd.
Engine stumbles and hesitates under appx 2k rpm while driving. If i rev it in neutral it revs fine.

If i unplug the egr it will run fine.
If i unplug the o2 senor it will run fine...
I replaced the o2 sensor which did not fix the problem.
The egr does open and close. I swapped with another used EGR and no difference.
If i leave the EGR vacuum connected and disconnect the EGR solenoid it runs fine.
Could the EGR valve still be my problem? What else should I check?

Update: Replaced the EGR valve and the problem is fixed. I used a EGR valve for a 1995 Cavalier because it was less than half the cost.
