Yes, when idling and driving.
Bad engine cushions can make the engine shake. bad spark plugs cause malfunction as the car starts running.
Several things can cause your car to stall and shake when you stop. Replacing the spark plugs and spark plug wires may cure the problem.
I'm not in expert, but it could be ( in winter time) that the car engine is still cold. But if its warm temperature outside, it could have something to do with the gas filter. Its probably blocking from the gas to get to where its supposed to go. It also could be your spark plugs, or wires from the spark plugs. You could check the spark plugs yourself. If the end of the spark plug is dark, like almost black, you need new spark plugs. If you look at the wire from the spark and its worn out, then replace them.
If your car is shaking it could be poor suspension alignment can cause a car to shake and vibrate, and other possible causes are bent or worn suspension parts, old tires, bent wheels and bad brakes. If your car sounds especially rough at speed, the problem could lie with the car's spark plugs and wires. Spark plugs fire more frequently the faster you drive, and the engine will sound rough when they begin to fail.
No,car will not run rich.Infact it gives misfires since escaping fuel will be the ultimate result if we use wrong spark plugs.
having bad spark plugs could effect how the spark sparks and when it sparks. new plugs is never a bad idea
Yes, spark plugs can cause a car not to start if they are faulty, worn out, or dirty. They are essential for igniting the air-fuel mixture in the engine cylinders, and if they fail to create a spark, the engine won't start. Additionally, issues with spark plug wires or connections can also lead to starting problems. Regular maintenance and timely replacement of spark plugs can help prevent these issues.
my sparkplugs are gaped to wide can that cause my car to surge and poor starting
How long spark plugs last depends on the brand of spark plug and the condition of the car. In a well maintained car, some spark plugs will last from 3 to 7 years.
This is a very general answer, as I don't know what "running bad" means. I would start by changing the oil filter and filling it with new oil. I find that quaker state is the best. Next, I would change the spark plugs. Bad spark plugs and low oil can often cause a car to jerk and shake whether your driving or just idling.
Old spark plugs can make a car misfire, run rough, and not fire at all.
