I know that this has been mentioned before but I can't seem to find
it. So hopefully you guys can help me.
I start my car up and it idles normally( 500 rpm/ 750 rpm ). I then
drive around for a while but as soon as I come to a stop eg
intersections or traffic lights the idle shoots up to 2000 rpm and
stays there for about 30 seconds to a couple of minutes. What's
going on?
Look forward to your replies

Quite a few things can cause this Vacuum leak,Idle Air Control valve
sticking,misadjusted, or defective, sticking throttle cable or
linkage at throttle body, throttle body itself,(don't turn the lower
screw on the adjustment on this) throttle position sensor misadjusted
or defective these are the most are the common causes. If it is the
Idle air control valve sticking they can be removed and cleaned
