Think of the last time that you had a tune up done. This sounds like a mis-fire problem. Try replacing your spark plugs, preferably not Platinum..because you cannot gap them, and have to use their gap. Bad experience with them. Replace spark plugs, wires, maybe distributor cap & rotor. If this doesn't fix the problem, listen for any vaccuum leaks, or check your PCV valve, and PCV valve hose. Sometimes they get pinched, and crack.. and doesn't take the fumes out of the block to get reburned. Could be lacking oxygen, check your air filter as well. What kind of vehicle (cylinders) is it? And does it happen when it's cold, hot, or both?
Bad fan motor or bad capacitor.
Electromagnets in motors are used to cause the motor to spin (rotate.)
Your motor movement and coordination may be affected. Hitting the back of the head could cause damage to the cerebellum
Usually, a 12 volt motor is DC. Changing the wires will reverse the motor.
A loose kill switch wire on your out board motor will cause the engine to lose power. As the kill switch loses contact the motor will begin to bog down or completely quit.
A failed cv shaft or a broken motor mount are most likely.
definant possibility. with a broken motor mount, the engine will lift up during acceleration thus causing vibration.
yes
lack of oil
yes
Debris in the hoses or reservoir could cause the motor to overheat. Also, running the pump without fluid could do the same.
could be the resistor on blower motor is bad
The thing that could cause a knocking noise in your car is the same thing that could cause it in all cars A rod that or a flat lifter. it all really depends on where the knock is if its higher and to the back of the motor, it could be a motor mount
Could be the starter relay
You have a misfire. Check the coil packs. If the first answer don't help also check your spark plugs and check your motor mounts and if that not it get you exhaust checked or do a compression test.
Freeze plug at the rear of the motor. Between the transmission and the motor.
if the motor is turning then it could be off the track or a gear might be stripped.
