Poor quality or badly worn spark plugs may exhibit a higher fuel consumption, rough/erratic idle, poor acceleration due to a higher gap. They may cause a slight increase in temperature although not enough to notice on the gauge--several degrees maybe. I'd look elsewhere for your overheating problems.
