Made this account to help my wife. She has a 2007 Camry LE. Bone stock and unmolested.

This morning while driving, she noticed a shuddering that scared her. She called me and parked the car as soon as she could. I went to drive it around and, as she had said, it was shuddering.

I drove it for a bit, neighborhood and highways, and took note of everything. The RPMs were low - About 500. I'm not sure where it usually idles, I rarely drive this car, but my Jetta idles around 900 so this seems strange to me. RPM gauge occasionally bounces around at idle. Once the car gets moving there are no issues. Only at complete stop. It feels like the car is about to stall.

I drive a manual and if I keep it in gear while approaching a stop it makes the same shuddering because the RPMs are too low for the selected gear. This is what it reminds me of.

Here is a video of what's going on under the hood. I am a terrible cameraman, but as you can see, the airbox is vibrating heavily. That's the most obvious place. The engine and intake manifold are also bouncing around, but it's hard to see in the iPhone video.

Thanks for any input you have!

 

Anybody?

 

If the engine otherwise operates OK at higher RPM, the reason the engine is vibrating is the idle is too low, should be around 750 rpm.

The engine uses an electric throttle not mechanical which complicates troubleshooting.

Suggest taking the car to a shop or dealer.

On the off chance if you have some mechanical skills inspect the engines air intake system for air leak from loose, damaged or disconnected vacuum hoses.

 

It seem difficult and need help of a pro...agree in bringing to shop where pro can have a look at it.

 

base on your video sounds like it's misfiring ,cel should be on if the CEL is on , pull the codes .using a obdII reader (autozone does it for free)
