ok heres the problem, it's been heappeing the last 2 months for some reason when the car is cold its a bitch to start i have to keep it at WOT for like 5 sec just for to catch alittle and then i feather the gas stumbles a bit for like .5 sec and idles like a champion at 1500-1700 rpm warms up a bit and drops down to 900rpm and holds strong the car drives fine all the power is there, so after i drive the car for a bit park it for like 2 hours go back to it it fires right up like it was a new car strange
but after i drive the car again and park it over night it starts all over again
so to sum it up
when the motor is cold hard to start
when the motor is warm or hot FIRES right up with no issue
no matter what temp it's outside 30F or 100F if the motor is cold it's a bitch
to start
please help
