Question on Boxster Engine Mounts

Hello nick! I've been feeling an engine vibration at exactly 1300 rpm, my car is a tip 07 Cayman S, I've changed Spark plugs and cleaned the throttle body, it is present in neutral and in gear when leaving the lights for example, have you heard of anything like this??? I've been searching in many forums a everybody seems to talk about 1900 rpm vibrations. does this sound to you as an engine imbalance or bad motor/trans mounts??? also no codes present for bad coils, when I rev the engine for example in neutral when rpms come down the car shakes.

Thanks nick!

Only with the lights on? Does it go away with them off? Worse with the heater blower on? if so, the additional load could be causing a vibration not being dampened by the motor mounts.

Hi Nick, it's exactly the same with accessories on or off.
