DO TRANSMISSION FLUID FILTER CHANGED IF YOU AT 100000 MILES,WHICH IT IS DUE,CHANGE AIR FILTER AND FUEL FILTER, CLEAN FUEL INJECTORS SEE IF YOUR POWER IMPROVES.TRANSMISSION NEEDS A HEALTHY ENGINE BEFORE IT WILL SHIFT RIGHT AND SMOOTHLY.

Prognosis is really bad, hate to tell you. Ticking comes from the valve lifters, losing lubrication due to lack of pressure and running dry. At redlights, when revs are at idle, oil pressure drops a lot, and engine really suffers. Have the vehicle taken immediately to a shop for proper diagnose and to see if engine can still be saved. The loss of power comes from the valves not actuating properly. Hydraulic lifters need oil at a decent pressure to "charge" , and if not charged, they will stay compressed, ruining valve lifting operation.
