The fan blade may be loose. You can determine this when the engine is off by moving the fan blade by hand or by watching it rotate when the engine is running. if its a real loud then i would check out the harmonic balancer. to check this. with the engine OFF grab the belt and try and move it back and forth if it does and u hear a noise than its the balancer. i had the same problem i fixed it my self saving $$$$$$$, but it was a pain....u need atleast 2 people to fix this. good luck On my 94 Buick Century the water pumb made a loud clanking noise at idle, which would go away when revved up. A day later the water pump seized up and the belt smoked up a storm where it rubbed over the stuck pulley.
The fuel pressure regulator maintains a constant predetermined fuel pressure regardless of engine RPMs.
An automobile engine usually shakes when it is being revved due the crank rotation. When revved in neutral, a torque is produced due to the reaction of the motor.
The engine has a short rev range, like a diesel.
There are many reasons why an engine will sputter when revved. There may not be enough fuel getting to the engine, there may not be enough electricity getting through the car, or the computer could be going out.
You need a tune-up
It will have/make 150 horsepower @/when revved to 6000 RPM.
It's because the thermostat is stuck open.
This guage is to register the RPM's (revolutions per minute) the engine is running. In short, how much the engine is revved up.
The thermostat is failing.
The engine was revved up, it rolled and gained lift then suddenly it was in flight.
