Could it be described as a misfire in the ignition under load? Have you returned to the transmission shop to get there assessment?

Yes I brought it back to the transmission shop and told me it was a missfire underload and before I brought the car to the shop I put a new egr valve I think it's that because you can hear the rpm's going up and down and the car smells and has kinda a rough idle thanks have a great day.
