Idle Issue
« on: November 07, 2018, 09:33:39 am »
Hi only had my car a few weeks 2007 2.0 petrol 147Bhp engine pulls well with no hesitation but when at idle revs sit at just under 750 and there is always a slight shudder as if engine is struggling to tick over but not to the point that it stalls and the rev needle will flicker up and down ever so slightly is this an idle control valve problem or possibly new set of spark plugs needed 73,000 miles and still on original plugs from day it left the showroom any help would be grateful.
