Hesistant mondeo

[woogie]

Hi all, bought a mk1 mondeo a few months back and it is sometimes very hesistant, you drive along the road and its kangarroing along. I have had full service, including leads, spark plugs etc. I also fitted another MAF sensor a few weeks back. Not sure what else to do. Maybe the coil pack? I am not sure but any help would be appreciated

thanks

is it just under acceleration (check throttle position sensor) or all the time? maybe an air leak or faulty injector(s).

No its when I am travelling at constant speed, someone mentioned to me the edg hose?
