He further stated that "a rough idle was typical for Northstar engines." Anyone else have this problem and/or know of any remedies?

    Thanks in advance,
    Hey Bob - Welcome to the CadillacForums! The Northstar does idle a *little* rough, but it's hardly noticeable. Unless you're extremely sensitive to it, I'm gonna guess that something is amiss. I'd start off with new plugs and wires. If that doesn't work I'd check the coil packs. In addition, I would do the engine oil flush, transmission flush, and coolant system flush if these were not recently done and documented. Your DTS is an awesome car but it needs regular maintenance to stay healthy and strong.

    Thanks for registering...let's see what the smart guys have to say about your rough idle.
