Questions 1-could be a spark malfunction(pre ignition)?
2-could be a coil malfunction ?
3-Lets suppose it could cause by spark failure,HOW ABOUT THO CHANGE the SPARKS for a colder like HKS-M45HL ?

Change your plugs first. This is usually what causes it. Only other thing that would cause hesitation at that RPM is improper fuel delivery but that would be very rare.
