Hi I'm new here I bought a fabia mk2 1.2 htp 70 07 reg done 55k a few weeks ago however whenever the engine seems to warm up the revs seem to hunt between 500 and 1000 at idle sometimes returns to normal when I press the accelerator car almost stalls and judders when it dips to the 500 mark had it tested by skoda no fault codes so they said they cleaned the throttle body soon as I drove off the forecourt it was worse then seems to just be when the engine warms up again now .
Took it to another garage tested head gasket and said there was no fault codes so I'm getting stumped been told it could be coolant temp sensor or the exhaust valves also an ecu fault or alternator or battery il drive ot to a garage when it starts hunting next time I'm driving it so they can see it doing it but just wondering if anyone has hd or solved this issue thanks
