Hesitation accelerating from stop
Replaced plugs/wires (both w/OE Bosh) to correct hesitation, only noticed accelereating from full stop. New plugs/wires have greatly improved the situation, but a slight hesitation still exists. Anybody experience similar issue?
Thanks in advance,

You probably have a dirty Throttle Actuator. If it is not clean as in the photo it must be removed to be cleaned, as it faces the rear of the engine.
Remove the air intake pipe and then have a look at it by using a mirror. If it is dirty then remove the 4 Torx bolts and clean inside and out with Throttle Body Cleaner. Do not use Carburetor Cleaner.
