My car drives fine, even under WOT. The exhaust smells a bit like coolant and it overheats once and awhile depending on my driving style on the highway(40-120 mins). I took out the thermostat and temp checked it for opening and it was a bit late..204 instead of the 186-194 the TSRM states. I've been told they can stick, could this be it. The other thing about the overheating, if I catch the temperature going up slowly, I can either shift up if I'm in a gear lower than 5th or let off the gas and it will settle back down. I find this to be very odd. I have had white smoke only when I first go WOT after the car has warmed up after sitting for awhile, but no other time.
