Hard to idle when cold first Start the car.

[Tony Hoffman]

The first thing I'd check is for vacuum leaks. Once warm the engine
electronics will compensate for quite a bit, but when cold it runs on the
base settings. A few common places for leaks are the diff locks(white line
under the hood) the vac canister (green line to the drivers side) and the
charcoal canister (inside teh passenger side fender liner).
