Has the lumpy idle problem started since the valve stem seal change or was it present before? If the problem has just started ,could you have damaged the valve head by forcing the valve against the piston during removal of the collets.Or maybe seals incorectly fitted.If the lumpy idle was there before especially when stoped in drive after a long run could the valves be excessively coked up.
