I have a gas stove that has been acting funny lately.Sometimes all of the burners will have sputtering orange flames that will last for that day.And it will be fine for a week and then do it again and so on.I have looked on the web and found a few things such as worn jets and pluged air intakes as possible causes but this would'nt explain the intermitent problems.I hate to call a repairman who may not see a problem on that particular day.Any help would be great!
