I recently posted a strange overheatng prob with my 2001 max gle 64k. When gauge would start to climb I would turn ignitio off then immedietely re-start and gauge would drop very quickly to normal position only to do the same thing after a few miles. Now I got a code after the service engine light cam on that ihdicates an O2 problem. I dont remember which one it was bt would like to know what the symptoms are for this and if it is something that I could do myself as I am fairly handy with car related things. I am having very poor mileage{ about 14 mpg city and highway mixed} and lately when first starting car it will hesitate and chug for about half a mile then clear up. Also occasional stalling at idle. Whats a "ballpark" estimate on the cost of said item with and without labor ? God bless you guys. Always great info from this group. Thank You! p.s. would the O2 have anthing to do with overheating? I changed the thermostat and flushed system before this code came up Always use premium gas
