hi guys...really need ur help..i'm living in malaysia(asia) hot humid in climate. previously i use NGK heat 7.fine.nothing's wrong....but i change to heat 6 for a try...after a month my thermostat jammed.i replace new original one.after 3 weeks also jammed.is it because heat 6 gives more heat than 7 and cause the piston chamber so hot that jammed the thermo.can this theory be true?
and i also experiencing everytime i run into traffic jam, the car feels so sluggish...i stop and start again, feel the car as usual.

so guys, im guessing the spark plug is giving me this heat problem...if u guys say yes, i straight away change back to heat 7(colder).people say if always high rev use colder plug.FYI, i alwys high rev.i mean everyday to work.

and during long traffic jams, if i on the aircond, the idle at start is 900rpm...after a while, start to decrease to 600rpm.during this time really hard to drive a car with 600rpm...if i off the aircon its ok....(this i think got to do with tuning)
 
what i think is if you dont have any problem with a colder plug, dont change it to a hotter one.

i guess it's better for you to change back to a 7.
