No good. I even installed a new power valve gasket just incase. I also made sure all the passages in the metering block were clear once again.

Just as I was about to sit down here and post, I remembered inserting a big screw driver into the butterflies while checking compression in order to have the air get to the pistons. I thought I had been careful when inserting but maybe that one butterfly is bent. Strange thing though, I drove it after checking compression and it ran wonderfully for several days.

Last thing I had done before this all happened is I had my headers welded.

Bottom line, that left front Booster is flowing fuel.
