? 92 S-10 wont run right until it warms up?

I have a 92 S-10 4cyl that kinda acts cold natured
When i first start it up in the morning and drive it down
the road it don't wont to take all the gas...Until it warms
up and then it does fine, i replaced the fuel filter, spark plugs,
and wires. It helped the motor run smother but did not
solve the problem.:screwy:

Thanks for {ALL THE HELP} I found the problem my self, one of
the vacuum hoses that been replaced at the very back of the motor
was replaced with a clear rubber hose and when you start the
motor it would collapse on it self. Making it not run right...
