Just asking a lil help from down under.
R34 Neo rb25det.
Every morning when the car starts, ( 8-12 celcius ) It will hold idle fine, and will warm up no problem, but, if I try to drive while the coolant is still cold, every shift it will bog out when I touch the gas, not stall, but like its hitting ignition cut or something. If I step on the gas, or rev higher before the shift happens then it can overcome the hesitation. Once coolant gets to normal, 70-80c, zero issues.
