every day when i drive my car to work it all ways cuts out at the same place. it is very iritating because it is allways at a junction as i come of the throttle and put the clutch down. it is like it is incapable of idling and it only really does it when it is cold. i cleaned out the idle control valve, replaced dizzy cap, rotor arm, temp sensors all to no avail. any help would be greatly apreciated (its driving me mad!).
