The codes are not showing up on the code list. Is there a description that you have for each code?

p1411 and p1413

The p1411 has to do with the secondary air system output being low. The other I can not find. The acceleration problem you are having could be many things. Lack of fuel pressure, timing, off, or maybe a air miscalculation. Are there any more codes.

no just those 2, but it says that is the Air pump alone with the EGR valve.

Could be air pump, vacuum not being applied to both EGR valves, solenoid, vacuum tubing. Need to do some testing.
