Engine shakes poss misfire. Injector values

Waynedance · Oct 23rd, 2017, 18:54

Revving the engine at standstill it will shake at approx 2k to 2.5k.

Would this be a misfire or engine mount, the top engine mount looks ok.

Does anyone know the injector correction tolerances, will get a diagnostic machine plugged in.

Does it do this when driving in gear ?

Can not really tell if it does it when in gear, checked again today and its more like 1000-1200rpm.

Theres a youtube video I saw a while ago which shows how you can test the vaccuum engine mounts. Might be worth doing a search.

In my case the vibrations were just glow plugs. 2 out of 5 threw faults on the diagnostics.

I meant when you're driving the car. I've heard that a failing DMF/Clutch can cause vibration at about 2000rpm....and those accounts have been while driving, as opposed to stationary.
