My cars' idleing and cold start problem is sorted now that i bought a new iacv.But when i drive WOT and slow down for a traffic light with clutch engaged the revs still seem to be stuck sometimes or it just goes up by itself.Could it be the cable?

 

check the cable for kinks. also check your throttle body to see if its sticking.
someone posted to spray wd40 on it and if the problem goes away then its sticking.

 

Ok will do thanks.Is it a big job to take the cable out?
