Take it to a mechanic
The ticking noise is the metal cooling.
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
Just a guess, check the alt. belt.
ticking noise is usually "lifter noise". if this noise increases in speed when accelerating then it is "lifter noise". just change your oil.and or maitain proper oil level.try using a medium to thick oil 20/30 20/50 , there is a product call lucas which also helps your oil lubricate the engines moving parts easier. i have use it, and it works , it takes a few miles but it works.
only way to stop lifters from ticking is to replace the lifter. ticking or noise from lifters is caused by parts being worn most times whenthis happens the nlobe on the cam that the worn lifter is on, is also worn,so you have to decide if it is worth paying for both to be replaced
the ticking noise is a small exhaust leak close to the exhaust headers or exhaust pipe near the engine.
if ticking noise is in engine, u most likely have a worn hydraulic lifter. check oil for correct volume and viscocity
yes, my 2000 grand prix gtp is losing power and makes ticking noise.
The fuel injectors make the ticking noise you hear at startup, especially when the engine is cold (colder temperatures).
you probly have a belt slipping, a can of belt dressing should stop the sound
A clicking noise, when accelerating, can be caused by a worn CV joint. The CV joint can cause the axle to collapse when it breaks.
from which part of your engine is the ticking noise coming from. if is the TOP it would most likely be lifter noise.try using a thicker oil.
