WhenI start my car multiple times in a row (More than once in ten minutes), the second start is always somewhat violent. I don't really know how to describe it...

It doesn't seem to struggle, it starts quicker than the first turn. But it sort of 'thunks', or something. It's really hard to explain. lol.

It only happens when the starts are in quick succession.

Other than this, I am not having any issues. It doesn't have any other effects that I've noticed.

I wish I could just make a movie of it and put that on youtube for you guys. lol.

 

does it revv at like 1500 for a minute then go back down to normal rpms?

 

No, it kind of does the opposite. It starts at around 500 (lower than normal), then goes up to the 800-1000 range (normal for winter/cold out).

Hopefully I'm not having a one of a kind problem, eh? lol.

 

I had sort of a similar problem when my injectors were leaking. Basically they slowly flooded the engine with the fuel that remained in the fuel rail after I shut the car off. This would cause hard cold starts (2-3 trys). Also, when I would try to start the car warm, it should start so fast, it was scary. Once I even over-cranked it. This may be because it was already "primed" from the leaked fuel.
