Len,

Mine sometimes stumbles when I first start the car for one-two seconds and then it runs very smooth. But it always starts right up...instantly.

I have wondered what it would be like if I just held the key on start until I was sure it passed through the stumbling period....this just goes against my grain, but I should try it.
