Seems that the fuel pump quit, check for fuel pressure, check for spark in the plugs and the fuel filter.

When an engine starts from cold,it does revs a bit higher than normal and then settle down after a few minutes of warming.This is quite normal.Now when engine is idling and then you start ac,it is quite normal that you will hear a higher noise/sound.This is because the compressor for the ac has activated.

Sounds ike bad valve stem seals to me.

these are known for carbon build up on the valves that cause several problems.this could be the problem as the carbon can cause the valves to stick a bit in the valve guides while its running and show up as a ticking noise with the gas applied.have the top end service done which cleans the fuel system injectors and any carbon build up on the back of the valves.if this gets bad enough it can cause the cam holders to break locking up the motor if the piston hits the valve.another thing to check is oil pressure and the lifters may be worn to the point that they need replacing.check the cam lobes as well if worn these can cause a ticking noise on acceleration.
