    A few weeks ago on a cold morning, the revs at idle went down to about 500
    then up to about 2000, and then continued to pulse between the two, the
    problem then went away but has now reoccured, but as well as pulsing from
    500 to 2000 revs, it sometimetimes sticks at 2500 revs.
    Can anyone offer any advice?, the engine is the 1.8 litre single point
    injection unit on a 1994 model. Looking at the haynes manual it appears
    to be the B18U engine. Could it be the idle control motor? Any advice
    would be appreciated.
    Thankyou in advance.
