Could be time for a tune up.
Usually a sputtering muffler means that a new catalytic converter is needed. The sputtering sound is the car misfiring.
The rear speakers in a 1999 Oldsmobile Aurora are typically 6.5 inches in diameter. This size is standard for many vehicles of that era, allowing for a balance between sound quality and space. If you're considering replacement, it's important to verify compatibility with the vehicle's audio system.
generally too rich somewhere. if sputtering 1/2-3/4 needle is too rich. if sputtering at wot, main jet is too rich.in generalsputter=rich, BOOWAHH sound=lean
check timing. timing advance. or slack in timing chain/belt
That is the air compressor for the ride leveling feature. It adjusts the rear air shocks when the back seat is occupied, or when passengers get out.
Your switch on the end of the turn signal arm has gone bad ( this is common on these models). It can be costly or difficult to replace
Old-style army jeeps were known for their rough engine operation, often described as "coughing" or "sputtering" and "clattering."
Sputtering is almost like a person spitting. The car runs but it doesn't have full power, could actually sound like someone spitting. Missing is when there is a consistent and constant slight jerking or vibration. Unless it is really bad it is hard to feel.
may sound like a joke, but isn't. the firing order is 123456
MINE SOUND LIKE A TEN
A sputtering noise from a gas stove oven when it's off could be caused by residual gas escaping from the burners or pilot lights. This can happen if there is a small gas leak or if the burner valves aren't fully closed. Additionally, moisture or debris in the burners can create a sputtering sound as gas moves through. It's important to check for leaks and ensure proper maintenance to avoid potential hazards.
A sputtering tailpipe typically indicates incomplete combustion in the engine, often caused by fuel system issues, such as a clogged fuel filter or faulty fuel injectors. It can also result from ignition problems, like worn spark plugs or malfunctioning ignition coils. Additionally, exhaust system blockages or issues with the oxygen sensors can contribute to this sputtering sound. Addressing these underlying issues is crucial for optimal engine performance and emissions control.
