I've recently replaced the plugs, wires, cap and rotor. They are all like
new with about 1,000 miles on them.  It accellerates poor and unevenly. Low
in the RPMs during the accelleration curve it has very low power, then it
hits a certain RPM where the power seems to nearly double. It does this most
evidently when the engine is colder and warming up. (Not stone cold, and not
so much when it's at normal operating temperature.

check your throttle position switches ... if they're off a bit, it
might do that. don't see how you can tell that it's only doing "one
cylinder", though ... any electrical misfire will make it stumble like
that. i kinda doubt the fuel pump or the injectors. and a vacuum leak
should make it worse when you accelerate or idle. i'd suspect an
electrical problem, something like the idle stabilizer or throttle
position switches or the rotor/distributor .... which brings to mind
that little black plug in the side of the distributor. check and see
if it's cracked or loose.

good luck!
