P0300

Misfires multiple cyl.

Is this to be expected with a big cam? It seems to happen on cold starts and the motor will backfire once or twice until it settles in and starts to warm up a little.

Any Predator people know if I can program this out?

TIA

Did you get it tuned on a Dyno using EFI live or HP tuners or something.

Not yet. I'm using a Diablo Predator and the open road. Actually, the car runs really well though. I'm amazed that the stock PCM with the Diablo performance tune tweeked on runs this good. The only issue I have is the P0300 on cold starts and once it warms up it sometimes has a hard time idling for a minute, then it settles out at 850rpm and sounds awesome. Here's a few clips.

Here's a cold start from this morning. It was 18F outside. I just got in and turned the key.

Makes me wish I had a car this cool

And a little bit of driving. I don't have a cameraman so it's just a short cruise.

I'm working with Jesse at Wiat4me to get a better tune, but in the mean time I'm playing with the Diablo and learning more.
