Hey Corbin..
What the problem you having is EXACTLY what me and Wicked is having as well.

Check out this post: http://forums.2gnt.com/dcboard.php?az=show_topic&forum=54&topic_id=2460&mode=full

We both are having the same problem.
We both have shielded cable to the crank position sensor but still no luck.

But good that you tried out the 4G63 power transistor already. coz that was my next attempt.

From the other post, me and wicked pretty much believed the RPM SURGE is what cause the choking of the engine.

So what exactly can we do to eliminate the SPIKE?

P.S. LOL, guess Corbin, Gilee (Me) and Wicked all have this problem. LOL.
