When I first get in my car and drive it for around the first 5-10 minutes it runs fine, but when it gets warm, the car will stutter/lose power when you try to get on it.

Things I have replaced/checked already:
Module on distributor
Cap/rotor/plugs/wires
mass air meter

What else could cause such a problem to where it runs fine for a couple minutes then the problem gets worse when you drive it longer.

I drove from brandon to plant city and by the time i got to plant city I could only use very very light pedal pressure to keep up to speed with everyone else. Then, when i drove back to brandon, everything was fine until the first couple minutes past by and by the time i got to brandon the same thing happened, only can put very light pedal pressure on it when accelerating, otherwise it will stutter, etc.

Any thoughts?

 

Is it running hot, losing water? possible head gasket. Any problems in the past with fuel pressure

 

Runs really cool and doesnt lose water, negative on the fuel pressure, im trying to check that right now, however

 

fuel filters cjanged when you swapped the motor???????

 

Negative

 

change them

 

unplug the IAC with the car off, pull the pill by the dizzy and set the idle screw. set the timing, play with the idle more. shut off the car, plug it all back in and i bet you'll be good.

 

Checked codes - nothing except the emmisions control stuff comes from the code scanner

 

change the fuel filters.......sounds like they are packed with shit. They are cheap.
