When cold (ie, around 0 degrees, colder it's even worse), the valves sound like a bad diesel engine. I understand this is an DOHC engine, and the oil might need to get up there, but it's ridiculous. When warm, whenever I'm at a stop light (auto tranny), the engine sputters, and gets worse when I use the lighter or the defrost (sounds like either the alternator is not giving out enought voltage/current, or the ignition wires/plugs are in need of a replacement.
Any ideas? I've already spent *WAY* too much on that car.
