What Causes Vibration ??

[IndyIan]

All motor mounts aren't created equal either, but it might be easiest to test if raising the idle speed solves the problem. Tickle the gas in D or R to raise the idle to 850 or 900 rpm and if that works, find the idle rest stop on the throttle body and see if it can be easily adjusted. I think on your car it should still be.
An extra 100 rpm won't hurt anything IMO.

I have the idle at about 950RPM still vibrations. Motor mounts sure did cut in down a lot. This is why I wondered if there was a trans mount or a a fifth mount that was missed.

It's so weird, smooth as heck at any speed through 85/90mph on highway....then you stop at a light and the wheel is like a lawnmower!!! shaking in your hands.

The vibration cannot be completely eliminated, Just the nature of the beast. 90-93 2.2L Accords also vibrate.

I had a 95 Camry. The wheel would occasionally vibrate like you describe but the rest of the car was so smooth and quiet that it never bothered me. Some of the motor mounts are hydraulic and are pretty expensive. Aftermarket ones may not be as good as the factory ones.

Did you try cleaning the ICV to make sure the idle is correct?

Overall I wouldn't worry about it. That thing will vibrate on for years to come.

I'm going assume I did not clean the ICV .... since I don't know what it is!!

Oh boy! Now I have to ask for what is a ICV?

I believe JB meant IACV or Inlet Air Control Valve. I'll see if I can post some pic to make this easier instead of trying to describe it!

Others may be able to describe it better than myself!

Here's the first thing that I came up with though, IDK that it's the best way to do this

Intake is all clean and still vibrating a lot. My buddy took it in and gave it a injector cleaning just to be sure. Still vibrating so he checked the mounts. The "new" (made in China) trans mount defective. New one coming in tomorrow. Hoping this is it!

I used aftermarket motor mounts on my 2002 Envoy once... it vibrated worse than the bad ones I took off!!

Ended up returning those to Rockauto and buying the OEM AC-Delco motor mounts. After that, it was so smooth I had to check the tachometer to make sure it was still running...

Is this your first 4-banger?

 

[BISCUT]

Yes, my first naturally aspired 4.

Wanted to follow up and put a finish to this thread I started. After replacing all 4 mounts, and the rear trans mount 2x's! The first one was defective. Cleaned out the throttle body and still vibrating. Soooo after my poor buddy went nuts!! We figured it was possible the after market mounts were FUBAR. After a Toyota OE upper and the rear trans....low and behold she now rides lives a Lexus...a 19 year old Lexus that is.
