Make sure your tail pipes,mufflers, mid pipes, are secure and not tapping on anything at the rear of vehicle. have a friend tap the gas pedal and watch when the pipes flex under exhaust pressure, may have to be under a load with brakes applied. If the exhaust system has been replaced the shop may had install it without checking clearances between pipes and frame. I had my exhaust changed in my 95 mustang gt from the headers back and the mufflers were turned 45 degrees, which only gave me a less then a half inch clearance near the frame. Every time I took off it would sound like my tranny was going to fall out! I hope this helps let me know what you find out.

A hole in the muffler would cause a knocking sound in your muffler. A loose exhaust pipe can also cause a knocking noise.

Your brake master cylinder may be leaking. Have it checked by a technician.

No.
Cause low pressure oil pump
what engine?
Tornadoes cause blackouts by bringing down power lines, either by knocking trees into them or by directly knocking over or even blowing away utility poles.
A bad harmonic balancer can cause a knocking noise. The harmonic balancer doesn't actually produce the noise, but it can cause the noise in the engine.
can you elaborate? engine noise? stationary/moving? ticking, tapping or a definite knocking?
you may have a rod knocking and you need to take it to a shop asap
