My Ascot motor car has erratic idle. The idle fluctuate between 1000 and 1500 rpm when the engine is cold. The cause the transmission not to change gear at the appropriate driving speed. Why is this and what solution do you suggest?

Check the coolant level.
Check the Fast Idle Thermo valve.
Check the idle adjust screw.
Check the IAC and coolant hoses, ensure they are not clogged.
