It started and ran like crap... I shut it down, and it ran a little better, but still rather shitty.

I drove into LA, about 15 miles, bucking, detonating... you name it... backfiring... ran like shit.

As I exited the 110 to the 101, it smoothed out. No more spark knock, no more back fires, ran like it should. Drove off the freeway, gassed it and it ran much better. Drove to the third floor of the garage, no problems.
