My Engine shakes upon start up! Need help!

Ok so i have a 99 TL and i just hit 100K and i have not yet changed the timing belt.

So iv noticed lately when it is warm out and if my car is already has been warmed up. Once i turn of the car and let it sit for about 20min to 30min upon re-starting the car, right when the engine starts up it shakes extremely violently for about 1min then it straightens up and is fine.

It does not shake in the morning or with a cold start, nor does it shake after you turn the car on right after driving it. I have no idea what it could be. I just changed the oil and up a little bit of engine oil that stops leaks.

Please help me.!!

Probably your engine motor mounts. Mine sorta does the same thing, my engine only shakes when I start up my car, and switch from R to D.

Could have a leaky injector.

Without further diagnosis it's just a WAG, though.

I have the same problem. I also just checked and loosened up the valves. Not the problem. There is a TSB stating to replace the fuel regulator on account of vapor lock type issues in the fuel rail...
