Had fluttering idle when coming to a stop. Cleaned throttle body, MAF sensor, and replaced air filter. Battery disconnected for few minutes to reflash computer. Still has erratic idle at times. No check engine light before or after repairs.

Sounds like a vacuum leak. The easiest way to locate this is with a can of Brakleen or carb cleaner. Run the engine and spray the locations that could leak-vacuum lines, intake gasket(s), and throttle body. When the engine speed changes, usually by speeding up, you've found the leak.
