Everytime I start my car when it is cold, it hesitates for a brief moment and then kicks in. Same type of sound if I were to accelerate the car at a high rpm while at idle and just before the meter goes back down at the point right before it touches the bottom.... I immediatly hit the gas hard and it feels like its going to stall but, it's basicly hesitating for a brief moment then kicks back in.

This hesitation while starting from cold sit has just resently been going on. I guess I never noticed it before maybe because it wasn't as severe. Now I am really noticing it and getting a little paranoid.

Ive changed the spark plugs, wires, distributor cap, rotor last year FEB.

Any help will work. thanks
