Idling for your model should be between 600 and 800 rpm. If lower than this, check for air leaks/splits in the vacuum pipes paying particular attention to the throttle body boot pipe. If you cannot find anything, then I suggest a good clean of the ICV (Idle control valve).

Thanks for the quick response,my engine idles at 530 in neutral and 510 in drive so it sounds a bit low,I shall check the points raised,where is the ICV located please.It seems to set up a vibration at the lower revs.

Good thinking Batman,I'll have another go tomorrow.I found the rubber tube that joins the small plastic pipe to the f connector was perished so that was worth changing.I like the look of your car Neal.
