I need help. My van has pulled up many codes but the one that is the same and the only one that comes up now is PO601. when I start the van it just dies out very quick if i am not moving. After looking at the engine when it trying to run i smelled a lot of gas and noticed a lot of gas in my air filter. Is the PCM just dead and telling everything run backwards or do i have 2 different issues. Thanks for your help

Well that code tells me you have an internal failure in the PCM, if you haven't done it yet, I would go to Auto Zone for a free code scan, beyond that I am clueless.
