It's probably defective egr stealing power causing ecm to give the engine less power. My cousin's columbia lost 20% of the power.

EGR related. Is your fuel mileage dropping too? My dad had a similar issue, it wouldn't set a code because it wasn't that bad. But, power and fuel mileage were down. Then, a CEL came on, EGR valve was replaced and power and fuel economy went back up. Some of these shops just irk me. They see the same engines every time and they can't figure out what' wrong with them?
