Engine vibrating

While servicin engine was out of the car,
now the engine vibrating, some times brake is not working properly
and without accelaration rpm around 1800, car is moving faster
speedameter and rpm meter is not proportional
now the main problem is engine vibrating '
is it due to air and fuel mixing prblem?
Fuel supply is ok, plz suggest

I recently took my car to a Quality Auto Center Because of the heavy vibration that I felt coming from the engine. I especially felt the vibration when the brake pedal was being pressed at a stop light. He replaced 2 engine mounts in the front that were not that worn and he said that would ultimately fix the problem. Two days later the vibration is back again. Could this be something wrong with the engine or should I take it to a dealer for a full diagnostic test?

Thank you

You nailed it the was the balance shaft housing worn out I got a new one for $341.00 all fixed I love this site. Thank you

When I'm stopped at a red light, there is a very low rumbling, so low, that it's hard to tell if I hear it's a noise, a vibration or both. The vibration I feel is in the brake pedal.

My mechanic added some 44K but that didn't solve it.

Thanks.

Hi,

I tried it out in my driveway where I could concentarte just on the noise. Here's what I found.

1. It doesn't start until I drive around the block to warm it up a little.
2. It's definately more of a vibration than a noise and I feel it both through the wheel and the brake pedal.
3. I feel it in Drive, whether I use the brake pedal, the parking brake, or both.
4. I don't feel it Neutral or Park, whether I use the brake pedal, the parking brake, or both.
5. I don't now what the relay is but there are no lights flickering while it happens.
6. I also checked it with the fan and A/C on and off, and both are the same.

Thanks

Hi,

There isn't any jerk when shifting into either Drive or Reverse. Also, the vibration is the same in either Drive or Reverse.

A post on this website, about an older Camry, suggested it could be either the EGR or the Idle Air Control. Is that possible?

If it is, should I have my mechanic look into the motor mounts first or the EGR and IAC?

Thanks

Hello, while in Neutral or Park my car idles at approximately 650-700 RPM and I feel no vibration. When I put it in drive, but with my foot still on the brake and the car is NOT in motion the idle speed drops to 550-600 RPM and the car starts vibrating.
Is there any sort of adjustment that I can perform myself without taking it to the shop

Thank You.
