here is the situation :
i have heat when the car is at higher rps i.e. above 3k rpm
when the car is at idle the temp of the air goes almost as cold as the outside air.
after awhile of driving the temp of air is ok at idle( what i have the temp dial set to) sometimes ......
i have been monitoring this for about 2 weeks and there seems to be no pattern or situation that seems consistant.
any ideas / suggestions ???
