It's dangerous to run on a bad cylinder. It causes the vehicle to lose power which means that it increases the risk of getting into a vehicular accident.
A "Bad cylinder" or "dead cylinder" is a cylinder with Low compression psi. Symptoms: rough running low power can cause high oil consumption
The cylinder has a bad ring, is cracked or has a hole in it. In any case, your car is running on 7 cylinders which isn't good.
Cylinder is bad need toreplace
It could be very bad, it will eventually cook the motor. Gases and fuel keep trying to go into the cylinder making the cylinder have no place to put eventually bending valves or breaking a rod. (neither of which are good thing)
Very bad gas mileage. And can prematurely plug your catylitic converters.
Uneven running, bad fuel consumption
First check plugs to see if they are bad.
If it is a bad leak it will keep it fron idleing. While the engine is running you can spray some carb cleaner over the vacuum lines including intake gaskets when the engine changes sound or dies you have found the leak.
If you're talking about a single cylinder (#8?) with this question, keep in mind that spark is not the only reason a cylinder would misfire. For example, a bad/clogged fuel injector, poor compression, or a bad ignition coil (if you have one coil for each plug) could also cause this code. Possibly burnt valve on that cylinder. Run a compression test.
A fuse doesn't go bad. It protects a circuit. If the circuit is overloaded the fuse blows. If your Nissan is running sluggish, it is not a fuse going bad.
No. the valve seal basically keep the oil that's on the head from running between the valve seat and the valve. If the valve seal is bad you'll usually see smoke when you first start the car . ( your burning off the oil that wept down into the cylinder over night.
It might be allergies. I have really bad allergies, and sometimes that happens to me too.
