holding back hesitation bogging down

[N_Jonesy]

hi people i am still having major hesitation problems with my clio ph2 172

it is very hesitant and holding back or bogging down although there is fuel starvation on acceleration

car has had a new crank sensor swapped the temp censor for another, i have had the emissions checked and they are spot on would pass an mot as they are
i have today checked the plugs ngk iridiums and all seem fine , swapped the accelerator pedal for another one and still the same
checked theearth strap ineer wing to gearbox
car starts fine but intermittently bogs down to the point where it is un drivable
really dont know where to go from here with this but open to any suggestions
thanks

Have you had the car plugged into a diagnostic machine ?

Could be the coil pack failing, knock sensor (causes retarded ignition), fuel pump on its way out, MAP sensor.

There are quite a few possible causes, even down to the fuel used........
