Fluttering sound from exhaust runs rough engine light on lack of power

Hello, first it'll be important to find out what trouble codes are set, and this vehicle is OBD-I, so the codes will be very basic. Yet, they are very important to know based on the current symptoms. Sounds like an exhaust restriction or an air intake restriction based on symptom alone. Hands on testing is needed; there's really no guidance further to give without a hands on assessment. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Your Maxima’s symptoms—fluttering exhaust sound, rough running, and a lack of power—suggest a few potential issues. It could be a problem with the fuel system, such as a clogged fuel filter or failing fuel pump. The sputtering and dying at stops might also be due to a malfunctioning idle air control valve (IAC) or a vacuum leak. The check engine light will have stored codes that can give more insight into the issue. It’s a good idea to have those codes scanned and interpreted to pinpoint the problem. If you need any further advice or if you'd like any help finding a trusted RepairPal shop in your area, please feel free to call us at 877-913-1554!
