and this doesn't happen if the A/C is not on... right?

and does this occur when you start stepping on the gas pedal or during acceleration in general?

It happens when i start stepping on yhe gas pedal especially with low gears.Do u recommend putting her on a scanner?

i am suspecting the IAC... it might be acting up and causing this problem

put it on a scanner and see the activity of the IAC during ignition ON and when A/C is turned on during idle

check the fuel pump pressure and spark strength

make sure you don't have any vacuum leaks or intake restrictions

if you do have your cel on then get her scanned

I have just been to Mohamed El Sayed in Dokki ,the guy is really polite and knowledgeable.He put the car on the scanner and started to take some readings.Later he told me that everything is normal but he suspects the coil so we changed it with another one he has .Nothing changes.Finally he said that the car is normal and i have to drive it more smoothly.The hesitation is still on, i really donot know what to do

that was my feedback about my visit,do you have any suggestion?

hesitation in most cases is an electrical problem... we have established that your coil pack is fine... what about your spark plugs and spark plug cables?

use a multimeter to check for the resistance of all four spark plug cables... if the readings are not consistant then you might have a bad set of wires

if your OEM spark plugs are Champions then those are total POS...throw them away and get a set of NGKs

split fire wires are nice... but they are very expensive (some 360LE) and you have to cut them yourself and install the ....l sockets yourself to make a kit that fits your car

it took me two days to get the set ready for use... if money is no object and you got the required skills and time to do it then by all means go ahead and get yourself a set
