Ok Got a Check Engine and got the onboard code button light to blink finally after a good test drive. I'm getting 20 blinks.

I held the button for 7 seconds and couldn't get it to clear the code though.

Another interesting thing... I'm getting a smooth fire at 2-3k or so. Idle misses pretty good but 2-3k in park seems fine. Also seems like it is fairly smooth at WOT. If I hit 4k in park it's stuttering like it's rev limited. Before the OVP fuse change it was right at 3k when in park.
