She still surges at about 1k-1.5k rpm, I've replaced the cap, rotor, wires, plugs, fuel pump and filter, cleaned the throttle body but made no adjustments to it. What's next?! She runs great at full throttle but jumps a little at idle and wants to die at the mentioned rpm's. Oh yeah, also won't stay running when cold 'til temp. is all the way up.
