Hello,
Lately i've been having trouble with my motor. At idle, the motor sputters and the idle bounces around slightly. If it's a cold start, the idle will dip down to almost stalling point for a few seconds. Also, if I am rolling, and I slightly step on the throttle, the idle will dip down and there will be a huge power-loss and nothing will happen for a couple seconds. That gets worse if I am on a hill, the car will not move with the throttle 1/4 down for few seconds.
Things I checked/replaced:

Sparkplugs
Sparkplug wires
Distributer cap
Distributer
All hoses are good
Idle air control valve is working

I'm stumped!
Thanks for the help,
-James
