why do i always have to heat the engine up with a hair dyer for it to kick over?

even when its warm like it is now 55c i still needed to do it...



my t-maxx .15 never needs the hair dyer even when its 20s outside.


at first i thought it was just a bad plug but i have a new one in it.


when i take it with me to work which i drive it in a big parking lot it sucks when i have to take it back in the truck and turn on the heat and wait for it to heat up...
