So i have an 05 equinox 2wd with a v6. When we are on the highway the engine has a stutter. it almost feels like we are going over bumps but it is definitley the engine. It also does it when going up steep hills. Just had a tune up on it. anyone else have this problem?

Have not had this issue, but when the tune up was done, did they replace the fuel filter? Also did they check the fuel pumps output? It kind of sounds like its starving for fuel under a big load. Just a thought
