2003 Buick Century car is making a strange noise

Cannot diagnos the nioce without some more info. You say car will die when wheel is fully turned and car is moving slow. Sound like a loss of power. Here are some things to look into: Engine lacks power. See one of the following: 1.) Incorrect ignition timing. 2) Fuel filter clogged and/of impurities in fuel 3) Faulty or incorrect gapped spark plugs. 4) Air filter dirty. 5) Spark timing control system not working properly. 6) Faulty ignition coil(s) 7) Brakes binding. 8) Auto Trans fluid not correct 9) faulty distributor cap or wires 10) EGR system not functioning properly. 11) Use of sub standard fuel. 12) Low or uneven cylinder compression pressures 13) Air vacuum leak at intake manifold or plenum. You can forget number 7 at this time. Have you been keeping up with tune ups? Donate a few bucks for a pro's help.
