Subaru Forester: The engine on my 2008 Forester shudders/vibrates

Customer Question

The engine on my 2008 Forester shudders/vibrates whenever an electrical draw is used (power windows, A/C). The RPM does not seem to change, but it is as if it is idling very rough and feels like it might stall. This began a couple weeks ago. Also, when starting up, there is an initial thud as the engine starts that began about the same time. I had the engine tuned up and the timing belt replaced less than a year ago.
Any advice or ideas you can give me are greatly appreciated!

Hi please check ignition wires and ignition coil a lack of spark could cause your rough idle and hard start
