Cold starts on my STi have become a bit of a pain on occasions lately. Usually have to give a tiny bit of throttle as the starter turns the engine and it may give a bit of a splutter as if the spark is weak. The battery is brand new (60Ahr 600CCA) so no probs there. Once running, it immediatly settles at the correct fast idle - 1500rpm It's just the initial firing that's the problem. Electrical connections at the throttle body are clean, crank pos. sensor clean etc. and the temp sensor is working fine according to the SECS engine temp. readout. Any more suggestions??
