Tremor when idle but if it is above 1200 it is smooth

[markus_74]

hello

want asking why my engine has a tremor and I feel it at my steering wheel.

it is only below 1200 rpm only especially at idle, when i start to rev it will smooth.

does it is injector need to clean and calibrate? or something?

thanks
Markus

could be injectors,could be the idle control valve,try giving the valve a clean and make sure its buzzing when you turn the ignition on...other than that mate could be an air leak...weak spark plug...

I would say your not firing on all 4 cyclinders when idle. Pull the leads 1 at a time and see if it's the case..

What engine is it my friend?

was asking because I had the same problem with my m50 and found out it was my rocker cover gasket had gone and was seeping oil into the sparkplug wells,and they were full of oil,I cleaned them out and everything was fine!

Probably not yr problem,but somthing to rule out.

have you checked your engine mounts?

Engine mount is OK, spark plugs all new, but will try to check the leads cable
