Are you referring to a vibration in the ride of the car?

[MMamdouh]

sounds like your mechanic have no idea about what he is doing.

first we need some more feedback from you:

1- do you have a CEL?

2- how old are your fuel filter?

3- how old are your spark plugs?

4- how old is your timing belt?

5- when was the last time you cleaned out your intake?

6- ever cleaned up your injectors?

7- does the vibration occure while the car is in neutral or does it have to be in gear?

8- does the engine overheat or lose power?

9- any other engine complaint other than the engine vibration?

and last but not least ot to a real mechanic.

thanx man ..
1- what is a cel

cel is a check engine light. What MMamdouh was asking is if your check engine light was on or not.

[daewooluvr]

broken motor mount?

[MMamdouh]

broken motor mount?

could be that but it doesn't expain the loss of power... will not harm to check them anyways.

1- As Shaun explained... the CEL is that orange engine light that is on your dash... do you have this light on while you are driving??

2- replace it... it might have nothing to do with the vibration but the manual says to change it every 40,000 Kms, it is way too old and will cause future problems.

3- over and done with.

4- replace it... it is getting old and might snap and if it did you will bend your valves and will cost alot to repair.

also it might have lost some teeth and messed up your timing, does the car idle smoothly?

5- might need cleaning but that is not important right now.

6- over and done with

7- it is totally engine related... got nothing to do with gerbox, CV's or suspension.

8 & 9 - you have a vibrating engine that loses power... so when you reach those 2000 ~ 3500 rpm it vibrates AND lose power... more like power is going into the vibration rather than to the wheels... right?

from the feedback you gave i only suspect a timing belt... but still the car idles fine and seems to be doing OK so at lleast check it for wear and better replace it to avoid future trouble.

also what Shaun said about the engine or tranny mount could be logical too so check all engine and transmission mounts for wear, this will help on the vibration issue.

aside of that... replace your fuel filter and clean up your Throttle Body and Idling Air Controller (check the How to section) this will help in the lost power issue.

keep us informed with the developments on this subject
