My tdi engine shakes alot at idle

I've had this problem for a while now and I'm assuming it's the injectors. Soon as I touch the accelerator the sound goes away as the revs rise. I've used forte injector cleaner which helped abit but problem is still there

I would suggest you check the injector loom, then camshaft for wear.
