What else can I help you with?
How do you fix it when the ribs on the lowest pulley come off on 1990 buick century?
I believe that is the harmonic balancer. If that has failed, you will get engine vibrations at the lower speeds. It should be replaced.
What would cause an engine vibration on a 98 dodge neon the vibrating happens at all speeds at idler even if the engine is working in parking or neutral?
Not running on all cylinders? Bad harmonic balancer?
My 95' 305 vibrates at freeway speeds?
Before looking at engine possibilities, check the tires, suspension components, and universal joints. If all is well, check the harmonic balancer to see if the elastomer has worn out.
What is the layer of rubber between the two pieces of metal that are mounted to the stub on the end of the crankshaft called?
The assembly is called a "Harmonic Balancer" or "Harmonic Damper" in Europe. The Rubber acts as a damper to smoth the engine vibrations at certain speeds. The Rubber is not available seperately so most people won't know its called a "Damper"
How long can you drive your car with a bad harmonic balancer?
That's an odd question, first who told you the harmonic balancer was bad? Balancers are mounted on the crankshaft at the factory, and it is actually just a weight attached to the end of the crankshaft to offest the firing of the pistons producing a smoother running motor. Harmonic balancers do not go bad, EVER, unless they are removed and damaged during engine repair (unlikely, very unlikely). They can be re-installed incorrectly after major engine repair, or simply left off due to negligence on some cars after major engine repair but I have never heard of a balancer going bad, as it is not a part that can actually fail. Harmonic balancer is a fancy word for weight, however if it has been removed or severely damaged due to impact I would strongly suggest having it fixed immeadetly as the unbalance can actually warp the crankshaft at high speeds and destroy your engine. Hate to keep driving this point home but harmonic balancers do not go bad, you should seek out another mechanic to check out your car, if I were still a mechanic I would only have told someone that if I was trying to rip them off due to their lack of automotive knowledge, or get them away from my shop because they were annoying or a problematic customer. (sorry)
What factors decide the frequency of vibration of an air column?
The frequency of vibration of an air column is determined by its length, the speed of sound in the medium, and the mode of vibration (whether it is a fundamental frequency or a harmonic). Longer columns and higher speeds of sound result in lower frequencies, while shorter columns and lower speeds of sound result in higher frequencies.

Why car crashes more dangerous at higher speeds than at lower speed?
Higher g's produced at higher speeds are harder to survive.
Why are your RPMs high at high speeds?
Because your motor is spinning faster at higher speeds causing higher rpm's
What causes a 1990 Buick Century to shake and stall out when the car is slowed right down or stopped?
My 92 PA had a similar problem. At low engine speeds it would shake pretty bad. It turned out to be the harmonic balancer. You can easily check this by looking at the front end of the engine. It is the pulley that drives all the belts. If the rubber has deteriorated, it could be the cause of your problem.
Why are car crashes more dangerous at higher speeds than a lower speeds?
Because at higher speeds you have more velocity than at lower speeds transferring more energy to make a bigger crashing causing more damage.
What condition produces an engine vibration that increases in amplitude when engine rpm increased?
Could be one of several things from missing engine (1 or more plugs not firing) to the more likely Harmonic Balancer deterioration (rubber goes off after a while) or Torque converter being out of balance. The later 2 will typically become more prevalent as engine speeds increase regardless of wheel/road speed.
