Vibrations! Engine mounts or bad timing??

Hello!

I feel always vibrations on idle. Lite more vibrations if i hit the gaspedal and around 1200RPM.

This is really not good.

What do you think it is? Change engine ruber mounts? Both of the or just one? Wicg one? Or is it the timing that is not correctly set? OR something els?

new spark plug and ignition cabels

THANKS!!

Did you set the ignition timing with strobo lamp and wire in diagnostic port?
It should be 10° before upper deadpoint.

I cant check it for exactly 10 degres because the plastic mark was missing.
But i had some vibrations before the engine was change also.

Why do you need to connect it to the diagnostic with the cabel?
Normal, 1 cylinder cabel and then + and - and ground and ten diagnos mode. ?

The cars engine value co and lambda and the rest was okay in the car control yesterday but can the timing still be off?
Thanks

Is the intake hose 100% OK? I mean the big rubber hose with the 90 degrees.

When they get old, they leak and take false air.

Hello = )

The intake house has been a problem but its seald with good tuct tape.
Can that give vibrations in the chassi??

the vibrations is not constant its more like brrr---brrr----brrr and most around 1200-1300 rpm.

Then when the engine is warm the rpm meter is lockt around 650rpm but the engine feels not like r-r-r-r-r-r-r-r-r-r-r more like r--rrr--rr--rrrr-r-r-rr-rr-rrr--rrrrr--r

if you understand my explaination = )

Why do you need to connect it to the diagnostic with the cabel?

Because ECU is changing timing!
So you need to tell ECU to go to std. setting.

OK,

Test the TPS. Set bridge in TEN and GND when engine running. If the cooler-vents turn on, you have to set it.
TPS Throttle position sensor
http://www.probewiki.de/TPS

than you set the idle RPM to 650 with bridge in TEN and GND in diagnostic port
with the little screw on throttle body

After that you calibrate the ignition to 10° before OT. even with bridge in TEN and GND.

Also check Ignition cables and the right firing direction

The TPS is set already!

Here is a video:
cold engine

the iphone is resting on the stearing wheel so you can see the vibrations i hope.
