Hello Z drivers out there......

i need some help with hard cold start problem.

1. no ecu code present.
2. hard start in the morning, it usually starts after few try.and fine rest of the day.
3. i replaced distributor assembly, full tuneup.
4. i get spark and fuel, but hard to start in the morning.
5. one day car wont start at all so i checked the code(nothing like fuel temp sensor or the coolant temp sensors other zdriver mentioned with there hard start issues). i got spark and fuel.
so i decided to remove the spark plug to see and find out that all the spark plug was wet.
i replaced the plug and it started right up, but same hard start problem next day.
anyone with the same problem now or in the past?
please help....
