iceberg 172
my mum has a 1.2 clio 16v 2004 and in the morning her boy friend starts the car and waites for her out side after a few min the idle starts to drop and struggles. the temp gauge apparently jumps up and when the idle drops it feals like its going to cut out but revs it self back up. only does this on cold days and i have changed the temp sensor any ideas could this be the tdc sensor. its ok after a 5 min and its warm
