I just changed the head gasket on a 1997 Rover 800 2.5 V6, it was running fine before but oil and water were mixing. when I finished, it started and run fine with loads of power no overheating etc although the idle was a little bit rough. the next day it was difficult to start would idle but would have no power, i.e. when I put my foot down it would either cough or backfire or stall. it feels like a fuel starvation problem. Any help is much appreciated.
