Can anybody share a copy of the 2005-2007 Dodge Dakota Vacuum diagram for the V6 engine? My check engine light is on with a random misfire OBDII code of P0300. Engine is seemingly running fine if somewhat fast idle so a vacuum leak or two is probably the culprit.

I fought this one a few years ago. Long story short it was a bad fuel pump that caused it. Running pressure was low and it had a bad check valve in it. The cylinder was misfiring at startup because of low fuel pressure, once up and running it went away. Get the pressure test kit from O'Reilly or Autozone and see what it's doing.

You can download the 2005 Dodge Dakota Factory Service Manual for free here. You can find pretty much any information that you'll ever need in the manual. Not much has changed from 2005 through 2011 Dakotas, so much of it will be useful for any 4th or 5th Gen (05-11) Dakota.
