you need to check what t-stat they recommend if you run the motor to cold then the computer will think the choke is on and richen the motor up. the lower the t-stat # the richer the motor will run. on most late modal motors the fans. come on at 225 degrees and go off at 215. with a 195 t-stat. you cant run the motor at the temp. you like, it has to be the temp. the computer likes. that's the reason you need to check all of the sensers. I don't know where the temp sensor is but if the water is 195 at the sensor then its gonna run rich, be sure that you tell the mech. that's gonna check for codes that you have a 195 t-stat in the motor. thanks, mike

ps- I think for that motor to run like it should then the temp. will be about 200 to 210, and its nothing wrong with that as long as it stabilizes there.
