I recently replaced the fuel pump and now it's hesitating when i accelerate and climb hills. I used a aftermarket part so i had to change the plug. Could this be the problem? The hesitation started right after and has just gotten worse. I changed the EAV but it didn't help.

Hello,

This could be a problem with your fuel filter. When you change fuel pumps sometimes you stir up your fuel tank and dirt and debris gets sucked into your fuel system. Your fuel filter could be plugging up from this debris, but that's what it's designed to do. I have included a link below for you to go to.
