      Whole car shakes at idle and low speeds

      Hi there,

      I own a 2007 S60 2.5t AWD and last night all of a sudden while driving I turned into my neighborhood and as soon as I completed the turn I noticed an automatic vibration as soon as I press the pedal. I thought the road was rough so i waited 2 seconds and pressed again but sure enough, it vibrated the vehicle again. It only happens at low speeds, for example if i were to coast at 70-ish MPH the vibrating wouldn't occur. The CEL this morning started blinking for 5 seconds and stopped after that. Could it be a low voltage problem? I've also seen upper and lower torque mounts could be causing the problem.

      I doubt the motor mounts would be causing your CEL to blink. Have the codes read and report back.

      I'm going to say electrical. Plugs? Coils? When did you change these last? What the mileage on the car?

      I concur with this. On my old '01 S40 (and should happen with our cars as well) this is one of the main symptoms you'll encounter with a misfire situation. Check and/or replace your plugs. If it persists, then check your coils. When this happens if you're able to, get a code scanner or keep one handy and DON'T shut off the car. It should appear as a pending code in your ECU if you are hitting a misfire that is not consistently happening. Good luck!

      Classic coil failure symptoms.

      Cylinder misfires, will be taking it into a friends shop tomorrow morning to look into it a little more. I think you guys are right coils are probably what's causing it. I will keep you updated on what happens tomorrow

      If you replace any, I'd recommend replacing all of them at once.

      Costly, but true. Kinda like brushing half your teeth. What's the point?

      I love hearing that! Good to know it is right again! Your car will probably get better fuel mileage now.
