I just started my 408. I had a tune on my LS1 but before I got my tune I wanted to make sure I had fire no leakes etc... so I had it running and I got the code.

I know its untunned and will get Monday. I just wanted to make sure I didn't have a problem when I get it tunned and delay it from being tunned right. In other words I want to make sure I don't have an issue before I get it tunned.

Specs are in my sig...thanks!!

I think it is code p0300. It may be caused by the case learn not calibrated properly.Which is probably the what is going on with your car. The pcm needs to be sync'd to the crank shaft.

With a cam you have to tune out the misfire detection in certain areas.

I thought this may be the case but want to make sure its not something I need to fix before the tune.
