Thanks for the info. I have an Po300 code and po301 and P0308 and sometimes a P0300 and P0304. It changes sometimes. I can't yet check my fuel pressure because there is no extra port. i have steady vacuum. I was thinking about trying the cam sensor. New wires and cap and rotor. Any ideas.
....and go to the UserCP at the top of the page, and edit your dignature. Put infor about your truck there and we will all know what you are working on.
Welcome to DF.
Figured at some point someone else will search this error code on the Forum (like I did). Replaced both the crank and cam sensors, replaced the flexplate (and rebuilt the transmission) - and low and behold, the problem resurfaced two weeks later. Fortunately the last time it also kicked on the alternator light. Ended up that the alternator was dying a slow death and the output fluctuation was likely impacting the sensors - that was kicking it into a limp mode and throwing codes. 2000 miles now and working like a charm. Don't overlook the alternator in your troubleshooting.
