I recently noticed that sometimes while I am driving and I need to speed up for some reason it sounds like its having a hard time accel. almost like I am pressing the gas on and off. It doesn't do this always and it doesn't matter if the AC is on or off. It sometimes does this too when the light turns green, but mainly after its picked up speed. Does this sound like something having to do with the fuel injection? I want to have an idea of what the menchanics should be checking, when I take it in, otherwise I feel they make up things to charge me more.
