The engine is making a loud knocking noise that gets louder when accelerating. It occasionally stalls, and I have to restart it.
The variable valve timing system uses oil pressure and solenoid control. If the system is not working properly or the oil supply is restricted to this system a knocking noise can occur which can get louder on acceleration and if the timing is not being correctly adjusted the engine could stall. A Check Engine Light may be accompanied with this so faults should be read out as well especially if the engine stalls. You may want to enlist the help of a mechanic, such as one from YourMechanic, who will be able to determine the type of noise, locate its source, and repair the issue to correct the noise and stalling issue.
How to Identify and Fix Common car Problems ?

Engine stalls can indicate an issue with a fuel pump, oxygen sensor, or possibly an electrical system problem. It can also indicate you`re running low on gas, your car is overheating, or that an engine component is failing, such as fuel injectors or spark plugs.
The most common reasons a Dodge Charger engine stalling are the fuel system, the air intake system, or the ignition system. Search our network of RepairPal Certified shops near you to speak with a technician about your issue.
The most common reasons a Dodge Charger engine makes a ticking noise are low oil level or pressure, an issue with the ignition system, or an exhaust leak.
A knock sensor, even if faulty, can not cause hard starting or stalling. To have your hard starting, as well as stalling issue, diagnosed, the recommended service is a hard starting diagnostic.
If the smooth rumble you`re used to coming from your engine is replaced with a repetitive tapping or pinging sound that becomes louder and faster as you accelerate, that`s a classic sign of engine knock.
Some of the most common sensors that lead to engine stalling include the mass airflow sensor (MAF), engine coolant temperature sensor (ECT) and manifold absolute pressure sesnsor (MAP). The idle air control valve (IAC) and exhaust gas recirculation valve (EGR) are also well known for causing engine stalling.
What to Look For: A bad fuel pump can cause difficulty when starting the vehicle, a rough idle, and stalling. Clogged Fuel Filter – The fuel filter filters the contaminants from gasoline. Over time it can become clogged, which slows the flow of fuel. In turn, the engine doesn`t receive enough fuel.
bad spark plugs or wires
spark plugs seal off each cylinder, so if one cracks or gets loose, you`ll hear a ticking noise. this is a common problem after diy tune-ups. your first step is a visual inspection of the spark plugs with the engine off and cool.
An engine with low oil or low oil pressure can make a ticking noise due to a lack of lubrication. If you are low on oil, it may indicate either oil consumption or an oil leak, both of which should be addressed as soon as possible.
Your Dodge Charger can last as many as 250,000 to 300,000 miles by taking good care.
Will a bad O2 sensor cause rough idle and loss of engine power? You bet. Moreover, you may also notice poor acceleration, engine misfires, and even stalling. Bad oxygen sensors disrupt all kinds of essential engine functions, including engine timing, combustion intervals, and air-fuel ratio.
FAULTY KNOCK SENSOR: SYMPTOMS
Engine warning light comes on. Error code is stored. Reduced engine power. Increased fuel consumption.
If you start to notice rod knock, this isn`t a problem that will just resolve itself—you must take immediate action and replace the rod bearing while also fixing any other parts associated with the sound. If you do not take action quickly enough, you might need to replace the engine entirely.
Although similar to valvetrain noise, piston pin noise often has a unique, metallic-sounding double knock and is sometimes most noticeable during idle with the spark advanced. This noise is often caused by a worn or loose piston pin, worn bushing, or lack of oil.
There are three major causes for a stalled engine: A lack of fuel, a lack of air flow and improper ignition. Running out of fuel is one of the most common causes of engine stalling, but dirty fuel injectors or a plugged fuel filter can also be the culprit.
Bad solenoid may be causing vehicle to stall.
A faulty crankshaft position sensor will be unable to identify the exact piston position, triggering an engine misfire. This causes your car to shut off while driving. A drop in performance, fuel efficiency, rough engine, etc., are some important symptoms of a damaged crankshaft position sensor.
The most common Dodge problems include faulty electronic gear shifters, low mileage engine blow-outs, rusting, wobbly front ends, and dashboards that crack easily. Dodge has been around since the 1900s, making it an American classic with over one hundred years of experience in the industry.
Dirty or Worn-Out Spark Plugs
Often, your car shakes when idle simply because it`s time to replace your spark plugs! When yours are dirty or worn out, they fail to fire in the right way. If this happens, they`re unable to ignite the fuel located within each of the piston cylinders on time.
An engine knock can usually be attributed to a detonation problem, which is why the knocks shouldn`t be ignored. Bad engine detonation can cause catastrophic engine failure if the problem is left unchecked. Techway Automotive can inspect your engine and find the cause of your engine knock.
A knocking sound is usually due to a problem with the internal components of an engine. Driving while you hear a knocking noise is not recommended. The more engine damage you cause to these internal components, the more difficult and expensive the repair job will be.
Once an engine starts to knock, the rod can fracture without warning. It could be the next time you start it in your driveway, or it could keep going for six months. Eventually though, the engine will blow and you`ll be stranded somewhere.
Engine knocking often occurs when the air-fuel mixture is incorrect. To counter this, you can add an octane booster in the mix. This can help ensure proper octane rating, which can then stop the knocking. The recommended minimum octane level in the US is 87.
