I have a noise coming from my engine when I give it gas. Doesn't matter how much gas I give, I still get the noise. This just started and it has been warmer the last week here. It sounds like a ticking but it sounds like it is air coming out. Kinda like somebody putting there hand in front of a air compressor nozzle and then removing it fast while it is blowing air.

Any ideas? Where to start looking? Thanks

 

exaust leak from the manifold or a loose spark plug , run your hand above the manifold to see if you have a leak you will feel the air pulses and go over the plugs with a wrench and see if they are loose
