Ok I have a 98 gtp having problems with car thinking its my alternator bearings? Loud squeak had lights dim also having problems with car rpms jumping up and down every now and no codes. when I was driving today it was not to bad just loud squeak when I let off the gas to cost it stopped and when I went to take turns felt like power steering was cutting out. Changed plug wires mafs that's all I can think of right now
