Yesterday I got in my car to go pick up some chinese take out. I crank the car, which had been sitting one day since last driven, and it immediatly begins shaking very noticably. It is also loud and I believe at a higher than normal initial start up revs. The front of the car is shaking from the engine. This goes on for about 15 seconds and then it stops. I was so shocked that I just sat there when it happened, I was about to turn it off when it settled down. Has anyone else experienced this? I am on my second engine, '06 oil consumption. This is the V2 handbuilt one. It has about 4200 miles on it and is not consuming oil. The feeling I had when the shaking occured was almost like an out of balance situation, which really concerned me. After it settled down I rode out to get the food and back with no problems. Drove to work and back today with no issues as well. Anyone with any possible causes is appreciated.

check ur transmission

 

Transmission seems fine, car was in neutral when starting.

 

Almost sounds like the timing was all screwed up until the ECU corrected it.
