I been having issues getting the car to start . I had a dead battery so I figured it was the issue . the car would start rev up and immediately shut down no matter what I do . after changing the battery and adding coolant because it was low . it starts and runs very ruff . the car shakes and there is a loud popping sound from under the hood . think its from the intake . if I put my foot on the gas it slowly goes up into the rpm and once I read 4K it revs normally without sputtering or pooping . anyone experienced this?
