Hello, in the last week in my 92 LS 114,000 miles I have noticed a vibration in the steering wheel and engine area of the car at cold start up. Sitting in the car the steering wheel will vibrate back and forth slightly and it seems the engine vibrates also. The vibration feels like a wave going through the car and you can hear the hum of the vibration. Once the car is warm it idles extremely smooth and the vibration is gone. I changed out the power steering pump a few weeks ago and flushed and bled the system. My first thought is air still in the system but after flushing I turned the wheels from lock to lock about 50 times. I also changed out the transmission mount last week, new plugs, plug wires cleaned the throttle body, new pcv valve and I am putting in new distributor caps, rotors, thermostat and coolant temp sensor this weekend. Any suggestions? Thanks very much!!

Check motor mounts and transmission mount while you are at it.

Just changed transmission mount. Motor mounts are on the list for the near future. I just seems to me if it were 100% the motor mounts the vibration would always be present?

this is why you are FEELING the vibration, but you still also have the problem of why there is a cold temp vibration in the first place

I paid a more attention this evening when starting the car cold. While rpms are around 1200 the car will vibrate then stop for a second then vibrate again. As the rpms decrease the vibrations get less and less. The vibration kinda rolls through the car. I'm definately planning on replacing motor mounts in the near future. Thanks for any info.

Don't wait to long, procrastination could lead to other problems down the line.

Planning on replacing them in a week or two.
