I have 1990 accord with swaped engine f20a4 to f20a7 and instaled gas instalation. When is colder wheater and lower outside temp the car has problems with cold start, it starts right away, works then it turns off... i start it up it up again give him a bit throttle and hold him for a half a minut then it works good withou throtle holding... i changed that thing ( dont know englihs name for that part ), thing that regulates auto throtle. when the car has worm engine and workin temp it runs perfect. What to doo? tbx for the time to read this bad english.
