a/c's work better while compressor is running at higher speeds... also, everyone should have a manual for their vehicle, and the library should have a professional shop manual available in the REFERENCE section...make copies of the right sections...good luck :)

What causes a 2000 sable to rough idle when cold but a smooth idle when engine is warm?
Most likely bad intake manifold gasket. When the engine is cold the engine shrinks which unseals the intake and allows a small amount of unregulated air into the engine causing it to idle rough. as the engine heats up it expands sealing the leak causing idle to improve. You should also get lean codes from the computer as the engine is running to lean. Very common problem with the DOHC engine. See "Related Questions" below for more
