As with all of these questions, the cause could be many things, but one common one is this: The clicking is being caused by a bad exhaust-manifold gasket, which allows exhaust to escape its normal route from exhaust manifold to pipe to muffler. And in escaping that route, the leak makes noise as often as the piston nearest the leak purges exhaust from the cylinder in which it is operating. Hence a clicking noise that increases in frequency with an increase in RPMs.
If it's not a valve issue or some other issue, this problem won't hurt the car; it'll just get worse and more noticeable as the exhaust continues to erode the gasket material.
Check for loose sparks plugs also, sometimes the smallest thing could be the problem, i had the same problem and that's what it turned out to be.
a "knocking" noise could be your lifters. and the ticking when accelerating and letting out of the gas is the same thing. check your oil and if it's full then you may need to think about either having them adjusted, or getting new ones. depending on what you have depends on whether or not you wanna sell it

I have the same problem, have traced it to a relay behind the glove compartment. But I have no idea which relay this is, have noticed if I depress the brake pedal just a bit the clicking stops. I am still looking for an answer.
If this is a general noise, it could be the transaxle. When you are accelerating, the engine is pushing the gears, and when you let go of the pedal, the vehicle starts to shift back down. If this is an engine noise, it could be predetonation or a valve problem.
that is the wheel getting ready to change gear
Check the belt.
Possibly nothing more than the brake pedal return spring catching on something.
There is an electronic relay switch which turns on the rear brake lights-It's located behind the brake pedal- It clicks when you push the pedal down, making contact.
It's a reference to driving, esp cars from the '50s. The throttle is wide open when the (gas) pedal is fully depressed. With really old cars the floorboards are metal so with the "pedal to the metal" your accelerating as much as possible.
Spark plugs need changing. Also check the wires.
Bad motor mount.
Follow the brake pedal up behind the dash. The pedal arm ususally operates a button that turns on the lights when the pedal is pushed. The button could be stuck.
