This study investigated the effects of injection on convective boundary layer Kuvshinshiki fluid through a porous medium in the presence of a heat source/sink. The equations governing the flow were modelled as non-dimensionless partial differential equations (PDEs). The transformed dimensionless ordinary differential equations (ODEs) were solved analytically using the perturbation method. Expressions for Skinfriction, Nusselt and Sherwood numbers were

obtained. The numerical values of the Kuvshinshiki fluid velocity, temperature and concentration at the plate were shown graphically for varied values of the physical parameters. It was observed that the velocity of the fluid increased as Dufour number, Kuvshinski parameter, thermal and mass Grashof numbers were increased and a reverse trend was noticed as heat source/sink increased.
