when i just drive normally, my car has an issue with being sluggish and then all the sudden it feels like all the cylinders kick in to gear. this only happens when im just normally cruzing. when i give it wot it doesnt do it? i changed the wires, cap, rotor, coil and tps. and fuel pump. i think i had this problem years ago ans i dont remember what fixed it
