Guys,I do have an issue with car. I have EFI automatic cuore. When the car is stopped and is in D gear its engine vibrates a little more than the actual and i can feel that the dashboard is also vibrating because of it. But if i press race a little vibration vanishes. Even if i changed the gear to N the vibration stops. The vibration comes only when i stopped car on signal or while the car is not running and is in D gear. A little push to race stops the vibration. And if the car is in Parking or Neutral gear vibration stops to very minor. Can anyone guide why it happens or the solution.May be i thought the foundation rubbers of engine are loose.
day light inspection of engine & transmission mounts shall be 1st step. fractured mounts cause such vibrations , shall be replaced immediately.

Engine mounts
Here's what I did to get rid of vibrations in my cuore auto:1. Engine foundations replacement2. Top-up of automatic transmission fluid.3. Increase race a little bit.
If mounts r bad then it should even vibrate on N.i think u must clean throttle body first.also check ATF and replace if it has completed its life.also check air filter spark plugs
It points to transmission when is the last time you changed your transmission oil
shifting lever to N & vibration stop, Transmission Mount is Faulty focus on that item before fiddling around with any other
No sir. Once mounts of transmission are bad as soon as car is in D 12 or R it give vibration.And it doesn't gives vibration on idle.. Secondly if rpm has been reduced as low as 300-400 it gives vibration too.
true ... default idle RPM is 1200 for Auto Cuore900 for Manual Cuore
Sure, i will try to fix it on weekend
it is recently changed
Guys the problem is solved now.it was not because of Tran mission mount or Engine foundation.
It was an electrical issue and relay was not working due to which it was vibrating badly.Once i replaced the relay and increase a little bit RPM the problem solved
Interesting... Added Relay to my list of cuore vibration diagnosis. However, ars you sure that relay is connected with vibrations and they did not go solely on the basis of increasing RPM?
relay for which electrical item ?? please share
@babarhyd @margallar time to learn
say what?
yes please.
it was because of both dear. RPM was also very low. Relay is also changed along with the increase in RPM.RPM is set to 1200 now
I am not sure but he open the dashboard drawer and pull it out. behind that drawer there was a lot of electrical circuits and component and one of the relay was not working. He told me that if you turn on your AC there is no impact on the RPM of your car its mean that this relay is not working. Turning AC on and off should impact on the RPM of your car but bcz that relay was not working so may car RPM was consent even when i turn on my AC. so when he replaced that relay car RPM started to up and down while i turn on my ac. he also set the RPM to 1200. now i can feel that is vibration less.
ok fair enough
That means the relay drive for IDLE UP was faulty., and engaging AC rendered drop in RPM causing vibration which is understandable
Thank you for sharing details
Exactly. this is what the issue was
From karachi where can we solve this problem ?
