Hello there. A few common faults will cause your 2004 Chevrolet Aveo to have a fluttering tachometer. The most common is a misfire condition, vacuum leak, faulty tachometer itself, or a wiring harness fault. In order to have this looked at, a qualified professional from YourMechanic can come to your home or office to diagnose the rough acceleration firsthand so that this can be addressed properly.
