The issue you're describing could be any number of things including worn ignition system components, fuel system components or even a MAF malfunction.

Start with the basics.

Does the problem happen when cold or after driving for a while? You indicated the problem only surfaces at low rpms under a slight load so that makes me feel you should take a peek at the easy stuff like distributor cap & rotor, spark plugs, and the spark plug wires. For about the same price as having the injectors cleaned, you can purchase the schraeder value connection kit and a can of real injector cleaner and give you injectors a proper cleaning.

it happens after driving a while, and when i have the a/c on...i know its not when the compressor kicks on because it has a different feel and i can hear the compressor kick on, the cap and rotor,plugs,wires,
and igniton coil are all "new" and from msd...i'll go by the parts store when i get a chance and get the schraeder valve connector and the cleaner and try that...and yes usmc302, its a respray but the guy did a great job...
