my motor (B16A) stutters/hesitates when i give it gas sometimes... not all the time and not at any certain rpm... sometimes it doesnt do it at all, but im guaranteed to be plagued with it every time i drive (it happens pretty often)... the weird thing about it is that it never happens when the car is cold, only after the motor warms up to the normal temperature... the computer isnt throwing a code and everything is normal except for this...

anybody have any idea what this could be? i have changed plugs, plug wires, distributor cap, rotor, rewired the knock sensor, checked spark, etc, i even ran a compression check... everything was fine... im completely stumped...
