Acceleration lag problem?

Many car drivers notice this issues.The car struggles to rev and accelerate from a stops.

In this cases,Feathering the throttle marginally helps the rate of acceleration.

Also problems like transmission overheating in short trips.
The engine generating frequent cooling clicks after you turn it off.
Will be noticed.Exhaust clicking or crackle is normal and if the gage is low to normal heating issue should not be a problem. Fuel pressure is an issue but needs checked first before replacing the fuel pump. A compression test will confirm a bad or jumped timing belt which will kill performance and not necessarily stop the engine. Has the belt been checked or changed?
If not,then inspect the timing belt properly.If its very old,worn out and damaged.Then replace the timing belt.

This details will help.Thanks.
