Replaced the crank sensor and it made no difference. there is a sticker for updated software on the PCM so from everything I have read it has the "death flash" I don't use the ruck much but it is racing season so I'm going to wait a couple of months then pull the intake and replace the pendulum gasket. I will keep a look out for a un flashed pcm or a SCT tuner to get the advance curve back to were it should be.
