Ticking under acceleration
Loose spark plugs, a bad pulley bearing, vacuum leaks, exhaust leaks. get a screw driver and listen for engine noise like a bad lifter or loose rocker arm..could be piston slap too..
I had a ticking noise and it was the A/C belt one side of it was gone! (strange) also check the PCV valve and the hose for leaks..
hope this helps...
