When was the last time you changed your O2 sensors? They are supposed to be changed about 60,000 miles. Could be responsible for rough idle and popping in the exhaust.
Otherwise it is likely a vacuum hose that is leaking.
Possibly the fuel mixture is too "rich" or has too much gas in the fuel to air ratio. This would make it idle rough or fast and the popping noise could be the unburned fuel igniting in the exhaust system on the hotter than normal exhaust manifold. One check is after the engine has been running for a while check out the exhaust manifold to see if it is glowing red (best observed in the dark of night) this is a good indication of a over rich fuel to air ratio, and is not good for the engine. This engine would need the fuel to air ratio corrected by a qualified mechanic.
A distributor going out typically does not make a popping or sizzling sound. Instead, you may experience symptoms like difficulty starting the engine, misfiring, stalling, or a rough idle. If you hear popping or sizzling sounds, it could indicate a different issue such as a problem with the exhaust system or ignition components.
To avoid popping the balloon during the game, handle it gently and be mindful of sharp objects or rough surfaces that could cause it to burst. Additionally, avoid overinflating the balloon to reduce the risk of it popping.
Check the Cats have not disintegrated.
white exhaust and rough running usually indicate possible blown head gasket.
Intake manifold leaks will cause the engine to idle rough and get poor fuel economy. An exhaust manifold will have no symptoms other than the sound of the leak.
If your exhaust pipe is clogged, it can cause a buildup of exhaust gases in the engine, leading to reduced performance and efficiency. You may experience symptoms such as decreased acceleration, rough idling, or a strong smell of gasoline. In severe cases, a clogged exhaust can cause engine overheating and even engine damage. It's important to address a clogged exhaust pipe promptly to prevent further issues.
Is it coming from the front? If so then it is a lower ball joint. If you're not too machanicaly inclined, I would recommend taking it to an automotive shop.
The sound you hear in your knees when you walk could be due to the movement of tendons or ligaments over rough areas of bone. This can create a popping or cracking noise known as crepitus. It is usually harmless, but if you experience pain or swelling along with the noise, it's best to consult a healthcare professional.
A bad mass air flow (MAF) sensor typically does not cause loud noises on its own. However, it can lead to poor engine performance, rough idling, or stalling, which might result in unusual sounds from the engine as a consequence of these issues. If you hear loud noises, it may be due to other problems in the engine or exhaust system that coincidentally occur with MAF sensor issues. It's best to diagnose the root cause of the noise separately.
no...sounds like an exhaust leak could also be a crack in the manifold
It's extremely unlikely. Much more likely is rough running (usually due to engine management fault) causing a lack of oil pressure. Also, keep in mind that an excessively worn engine can cause both low or erratic oil pressure and rough running, but this will usually be accompanied by a knocking noise.
