Help please,

Have had a few issues with the S idle, had the injectors cleaned which fixed idle issues but now the car struggles to start when its cold or been left for a few hours, have replaced all of the injector o rings and it still does the same thing also reset ECU with no luck

not sure what to try next?

Can you describe in more detail exactly what happens? Is the motor just bogging on start up or do the revs not come up?

On my 2001, when it's really cold out, and only in the morning, I'll start my car up and the revs won't even come up, so I just shut it off and start it again and the revs come right up like normal, or I'll just stab the throttle.

I've read that cold starts on S2000's in the cold are violent so if you could post in depth what the car does exactly that would help more.

Thanks, mine is also 2001,

well the S2000 always used to take the same amount of time to start, but since ive had the injectors cleaned and the fuel rail out it seems to take a long time to start some times 5-6 seconds on the starter motor, almost like there is no fuel pressure so i switched the o rings for a new set thinking that would solve it but it does the same thing, if the cars left for over 2-3 hours it takes ages to start.

Would it happen to be colder outside?

When the temp drops from 70 to 40f I find the 4cyl needs a little more to fire up.
