wrong plug gap, wires on wrong, cap is cracked, timing moved when you put cap on
If the car has high miles, try checking the catalytic converter. If it is clogged it will cause the vehicle to lose power.
A malfunctioning battery can't provide enough power to your ignition system when the motor is idling can cause sputtering. If there is not enough gas, that can cause your vehicle to sputter. If the spark plugs fail to fire will also cause your vehicle to sputter.
yes it can
Power brakes use engine vacuum to get their power. If the engine is out of tune, the loss of vacuum will cause it to run rough. Try changing the spark plugs.
Changing power steering fluid lines in your vehicle should not affect alignment.
try changing the spark plugs
Yes, fouled spark plugs can cause engine shaking, and loss or power. I'm not sure about knocking but I'd guess that too.
Your piston rings are probably bad. Which will cause compression loss, in effect you will loss power, and it will let oil trough and saturate your plugs.

hello, have you changed the spark plugs in this vehicle?
I'd suggest pulling the new plugs and checking the gapping. Replacing properly gapped plugs with improperly gapped ones can cause a loss of power. And if you replaced them yourself with "pre-gapped" plugs, check them anyway. A lot of the "pre-gapped" ones are incorrect. If you are a do-it-yourselfer just pop a few out and check the gapping. If not, take it back to the garage that did the work and tell them of the problem and ask them to check.
larger amounts of power to the vehicle with the use of less gasoline
