Default 1997 Es300 Strange Startup shake

So I had the timing belt done on her a week ago. Everything seems smooth, tach reads same idle values (750) and are as solid as they were prior. Also revs great.

However, in MOST occurrences when I start up my car, it DOES NOT shake once I try starting it, but only when it seems that the engine has successfully started (when you've revved the starter long enough that you know the engine has successfully started that you let go of the key).

It not a super violent shake, and it's one "instance" (not multiple shakes, just one). But I'm worried something wasn't tightened, or something is cracked. I never have a problem starting her, this is just something I noticed after a timing belt job.

Thanks all, drive safe in this weather!

This might be related to your other thread "1997 Es300 Weird Oscillating noise 35-50 MPH".
Something is definitely loose.
Who did the timing belt? You should take your vehicle back to that garage.

Thing is, I had the symptom of the other thread before this one. Cold startup isn't relevant either. Going back to the shop fairly soon. Also, the small shake is only seen and heard around the middle-ish part of the dashboard.
