Hello, occasionally when i stop and about to move off my protege takes almost 5 seconds to respond to the gas. Even if i press right down it doesnt respond.. lately it is getting worse and it also starts back firing at times. What can possibly be causing this? This car is not fitted with a check engine light.

Is your car EFI or carby? You car will have an engine check light if EFI, if it is not coming on with the ignition it may have a blown globe, check this first. You may have a problem with the throttle position sensor.

There is a data link connector under the bonnet see pic for location, do a scan and report any codes.

Valve timing, but if nothing has been done here I doubt that that will be the fault, worn spark plugs, double check all tune item and if the scanner you used has a live date mode, check throttle position sensor opening percentages are about correct with physical position of throttle valve.
