Compounds have high accuracy

Hi there, I am using Agilent GCMS 7890B and Masshunter 9.0. I just want to know why some of my compounds, I mean pesticides have high accuracy in spike samples? Please noted, I am not allowed to change any parameters of the method? Thank you.

What do you mean by "high"? 20% or 200%? Did you run the spiking solution to check it? Is the LCS ok? Are surrogates ok? Probably more of a matrix and/or sample prep issue than MS issue.
